FAQs on NEET 2025 Mock Test: Magnetic Effects Of Current and Magnetism
1. What is magnetism and how is it produced?
Magnetism is a physical phenomenon produced by the motion of electric charges, such as electrons, resulting in attractive or repulsive forces between objects. It is mainly generated by the movement of electrons in atoms and by electric currents flowing in conductors.
2. State the right-hand thumb rule and its application in magnetism.
The right-hand thumb rule states that if you hold a straight conductor with your right hand so that the thumb points in the direction of current, then the curled fingers show the direction of the circular magnetic field lines. This is used to predict the orientation of magnetic fields around a conductor.
3. What is the difference between diamagnetic, paramagnetic, and ferromagnetic materials?
Diamagnetic materials create an induced magnetic field in a direction opposite to the externally applied field and are weakly repelled by a magnet (e.g., copper, bismuth). Paramagnetic materials are weakly attracted towards magnets and have unpaired electrons (e.g., aluminum, platinum). Ferromagnetic materials show strong attraction toward magnets due to aligned magnetic domains (e.g., iron, cobalt, nickel).
4. What is electromagnetic induction?
Electromagnetic induction is the process of generating an electric current or voltage in a conductor by changing the magnetic field around it. This is the basic principle behind electric generators and transformers.
5. How can you identify the North and South Pole of a bar magnet?
The North Pole of a magnet is the end that points toward the Earth's geographic North when freely suspended, while the South Pole points toward the geographic South. Like poles repel each other, and unlike poles attract.
6. What are magnetic field lines? List their important properties.
Magnetic field lines are imaginary lines used to represent the direction and strength of a magnetic field. Properties:
- They always emerge from the North pole and enter the South pole outside the magnet.
- They never intersect each other.
- Their density shows the strength of the magnetic field.
7. Explain the working principle of an electric motor based on magnetism.
An electric motor works on the principle that a current-carrying conductor placed in a magnetic field experiences a force, as given by Fleming's left-hand rule. This force causes the coil to rotate, converting electrical energy into mechanical energy.
8. What factors affect the strength of the magnetic field produced by a solenoid?
The strength of the magnetic field produced by a solenoid is affected by:
- The number of turns per unit length (more turns, stronger field).
- The magnitude of the current passing through it (higher current, stronger field).
- The presence of a soft iron core inside the solenoid (increases field strength).
9. What is the Earth's magnetic field and how does it help in navigation?
The Earth's magnetic field is the field produced by movements within the Earth's core. It behaves like a giant bar magnet tilted slightly with respect to the rotation axis. Compasses use Earth's magnetic field to indicate direction, aiding navigation.
10. Is the magnetic field inside a bar magnet uniform? Explain.
No, the magnetic field inside a bar magnet is not uniform throughout. It is strongest at the poles and weaker at the central region, because the density of magnetic field lines is highest near the ends (poles) and more spread out at the middle.
11. How does electromagnetic induction differ from the magnetic effect of electric current?
Electromagnetic induction involves generating electric current by changing magnetic fields, while the magnetic effect of electric current refers to the creation of a magnetic field around a current-carrying conductor. Induction is about creating current; magnetic effect is about field generation.
12. What is Fleming's left-hand rule and Fleming's right-hand rule? State their differences.
Fleming's left-hand rule is used to determine the direction of force on a current-carrying conductor in a magnetic field (used in motors). Fleming's right-hand rule is used to find the direction of induced current when a conductor moves in a magnetic field (used in generators). The thumb, forefinger, and middle finger represent different vectors (force, field, and current) in each rule.
