Chapter-wise NEET Mock Tests With Answers and Performance Insights
Mastering NEET 2026 Physics: Focus on Magnetic Effects of Current and Magnetism
The chapter on Magnetic Effects of Current and Magnetism forms the backbone of modern physics applications in NEET. Understanding this topic is essential not only for theoretical clarity but also for scoring high in Physics. This section covers key concepts, solved examples, and practical strategies to help you succeed in Mock Test 2 and in NEET 2026.
Key Concepts: Magnetic Fields, Force, and Motion
Magnetic Effects of Current explains how electric currents produce magnetic fields, a discovery crucial for developing motors and electronic devices. The direction and strength of magnetic fields from wires, solenoids, and loops form fundamental NEET MCQs. You should be able to apply the right-hand thumb rule and Fleming’s left-hand rule fluently.
Remember, the SI unit of magnetic field (Tesla), the relationship between electric current and magnetic field (Ampere’s Law), and the behaviour of materials under magnetism (ferromagnetic, paramagnetic, diamagnetic) are tested annually. Direct MCQs also cover concepts like the magnetic moment, solenoid field uniformity, and Earth’s magnetism.
| Concept | Key Principle | Example |
|---|---|---|
| Right-Hand Thumb Rule | Direction of field around straight conductor | Magnetic field circles a current-carrying wire |
| Fleming’s Left-Hand Rule | Direction of force on a conductor | Force on wire in a motor’s field |
| Ampere’s Circuital Law | ∮B·dl = μ₀I | Field inside solenoid: B = μ₀nI |
Strategies for Solving Magnetism-Based NEET MCQs
Approach chapter-wise tests with stepwise logic. First, identify what is given: current, magnetic length, field strength, or material type. Practice visualization—sketch field lines, and use mnemonics for rules like “left hand for force.” In the exam, always check units: many NEET mistakes come from SI or CGS confusion.
Utilize the elimination method to rule out obviously wrong options quickly, especially in questions on direction or calculation. Memorize core values such as permeability of free space (μ₀) = 4π × 10⁻⁷ T·m/A, and the formulas for force between conductors. Consistent practice with chapter-wise online mock tests strengthens retention.
Why Regular Mock Testing Matters for NEET 2026

FAQs on NEET 2025 Magnetic Effects Of Current and Magnetism Mock Test – Free Online Practice
1. What are the magnetic effects of electric current?
The magnetic effects of electric current refer to the phenomenon where an electric current passing through a conductor produces a magnetic field around it. This effect is the basis for devices like electromagnets, electric bells, and moving coil instruments, and is described by Oersted’s experiment, which demonstrated that a current-carrying wire can deflect a nearby compass needle.
2. State and explain Oersted’s experiment.
In Oersted’s experiment, it was observed that when an electric current passed through a straight conductor, a compass needle placed near the conductor was deflected. This provided direct evidence that current produces a magnetic field around the wire. The direction of the deflection depends on the direction of the current, demonstrating the relation between electricity and magnetism.
3. What is the right-hand thumb rule?
The right-hand thumb rule helps determine the direction of the magnetic field around a straight current-carrying conductor. If you hold the conductor in your right hand with the thumb pointing in the direction of current flow, the direction in which your fingers curl represents the direction of the magnetic field lines.
4. What is the difference between a solenoid and a bar magnet in terms of magnetic field?
A solenoid is a coil of wire through which current flows, creating a uniform magnetic field inside, similar to the field around a bar magnet. However, a solenoid's magnetic field can be turned on/off or reversed using current, while a bar magnet's field is permanent. Both create similar external field patterns with a north and south pole.
5. What is the principle of an electromagnet?
An electromagnet is based on the principle that a current-carrying coil wrapped around a soft iron core generates a strong magnetic field. This field is temporary and exists only when current is flowing through the coil, making electromagnets useful in electric bells, relays, and motors.
6. State Fleming’s Left-Hand Rule and its application.
According to Fleming’s Left-Hand Rule, if you arrange the thumb, forefinger, and middle finger of your left hand at right angles to each other, and if the forefinger points in the direction of magnetic field while the middle finger points in the direction of current, then your thumb will point in the direction of force or motion on the conductor. This rule is commonly used to determine the direction of force in electric motors.
7. What do you understand by magnetic field lines?
Magnetic field lines are imaginary lines that represent the strength and direction of a magnetic field. They emerge from the north pole and enter the south pole of a magnet, never intersecting each other. The closeness of the lines indicates the field strength; closer lines mean a stronger magnetic field.
8. Why do magnetic field lines never intersect each other?
Magnetic field lines never intersect because at any point, the field cannot have two different directions. Intersection would imply the magnetic field has more than one direction at the same spot, which is not possible based on fundamental magnetic field properties.
9. How is the direction of induced current determined?
The direction of induced current is determined by Fleming’s Right-Hand Rule. If you point the thumb, forefinger, and middle finger of your right hand at right angles, with the thumb in the direction of motion of the conductor and the forefinger in the direction of magnetic field, then the middle finger shows the direction of induced current.
10. What is the importance of magnetic effects of current in daily life?
The magnetic effects of current form the foundation for many daily-life applications including electric motors, generators, transformers, magnetic compasses, circuit breakers, speakers, MRI machines, and many more. Understanding these effects enables the effective use and maintenance of electrical and electronic devices.
11. What factors affect the strength of magnetic field produced by a current-carrying solenoid?
The strength of the magnetic field in a solenoid depends on: (1) the number of turns per unit length, (2) the magnitude of current flowing, and (3) the core material (soft iron core increases field strength). Increasing the number of turns, current, or using a soft iron core all increase the magnetic field strength inside the solenoid.
12. How does Ampere’s Circuital Law explain the magnetic field around a conductor?
Ampere’s Circuital Law states that the line integral of magnetic field around any closed loop is proportional to the total current passing through that loop. It helps calculate the magnetic field at a distance from a long straight conductor, and is key in understanding magnetic fields in coils and solenoids.
