FAQs on JEE Main 2025-26 Mock Test: Magnetic Effects of Current and Magnetism

1. What is magnetism?

Magnetism is a physical phenomenon produced by the motion of electric charge, resulting in attractive or repulsive forces between objects. It occurs due to the movement of electrons within atoms, and is a property observed in materials like iron, cobalt, and nickel known as magnetic materials.

2. What are the types of magnets?

There are two main types of magnets: natural magnets, which occur naturally (e.g., lodestone), and artificial magnets, which are made by humans (e.g., bar magnets, electromagnets). Artificial magnets can be temporary or permanent depending on how they retain their magnetic property.

3. Explain the magnetic effects of electric current.

The magnetic effect of electric current refers to the phenomenon where an electric current flowing through a conductor generates a magnetic field around it. This effect was first discovered by Hans Christian Oersted and is the principle behind electromagnets, electric motors, and generators.

4. What is an electromagnet? How is it different from a permanent magnet?

An electromagnet is a temporary magnet formed when an electric current passes through a coil wound around a soft iron core. Unlike permanent magnets, its magnetic strength can be switched on or off and is adjustable depending on the current and coil turns. Permanent magnets maintain their magnetism without any power source.

5. State Fleming's Left-Hand Rule and its application.

Fleming's Left-Hand Rule helps determine the direction of force experienced by a current-carrying conductor in a magnetic field. According to the rule, if you orient your left hand such that the thumb, forefinger, and middle finger are perpendicular to each other—forefinger points in the direction of the magnetic field, middle finger in the direction of current, then thumb gives the direction of force (motion) on the conductor. This rule is applied in electric motors and generators.

6. What is electromagnetic induction?

Electromagnetic induction is the process by which a changing magnetic field within a coil or conductor generates an electric current. Michael Faraday discovered this phenomenon, and it is the working principle behind devices like transformers and generators.

7. How can the strength of an electromagnet be increased?

The strength of an electromagnet can be increased by:

  • Increasing the number of turns in the coil
  • Raising the electric current through the coil
  • Using a soft iron core as the core material

8. What is meant by the magnetic field and magnetic field lines?

A magnetic field is the region around a magnet or a current-carrying conductor where the force of magnetism acts. Magnetic field lines are imaginary lines used to represent the direction and strength of a magnetic field; these lines emerge from the north pole and enter the south pole of a magnet, never intersecting each other.

9. State the properties of magnetic lines of force.

Some important properties of magnetic field lines include:

  • They always form closed loops from north to south outside the magnet and south to north inside.
  • They never intersect one another.
  • Their density indicates the strength of the magnetic field; closer lines mean a stronger field.

10. What are the applications of the magnetic effect of current in daily life?

The magnetic effect of current has many important applications in daily life, such as:

  • Electric motors (fans, mixers)
  • Electric bells
  • Loudspeakers
  • Electromagnetic cranes
  • Transformers and generators

11. How is the direction of induced current determined?

The direction of the induced current can be found using Fleming's Right-Hand Rule. If the thumb, forefinger, and middle finger of the right hand are stretched perpendicular to each other, with the forefinger in the direction of the magnetic field, thumb in the direction of motion of the conductor, then the middle finger will point in the direction of the induced current.

12. What is the difference between diamagnetic, paramagnetic, and ferromagnetic substances?

Substances respond differently to an external magnetic field:

  • Diamagnetic: Slightly repelled by a magnetic field (e.g., copper, bismuth).
  • Paramagnetic: Slightly attracted by a magnetic field (e.g., aluminum, platinum).
  • Ferromagnetic: Strongly attracted and can be magnetized permanently (e.g., iron, cobalt, nickel).
