FAQs on Magnetic Effects of Current and Magnetism JEE Main 2025-26 Mock Test Preparation
1. What is magnetism in simple terms?
Magnetism is a physical phenomenon produced by the motion of electric charges, resulting in attractive and repulsive forces between objects. It is commonly observed in materials like iron, nickel, and cobalt, which can become magnets and create a magnetic field around them.
2. What are the main properties of magnets?
Magnets have several key properties:
- They attract materials like iron, nickel, and cobalt
- They have two poles: north and south
- Like poles repel, unlike poles attract
- A freely suspended magnet aligns itself along the north-south direction of the Earth
3. What are magnetic field lines?
Magnetic field lines are imaginary lines that represent the direction and strength of a magnetic field. These lines:
- Start from the north pole and end at the south pole
- Never intersect each other
- The closer the lines, the stronger the magnetic field
4. State the right-hand thumb rule.
The right-hand thumb rule states that if you hold a current-carrying conductor in your right hand with your thumb pointing in the direction of current flow, then your fingers wrap around the conductor in the direction of the magnetic field lines produced.
5. How does an electric current produce a magnetic field?
An electric current passing through a conductor generates a magnetic field around it. This relationship was discovered by Hans Christian Oersted and is the basis for devices like electromagnets and electric motors.
6. What is electromagnetic induction?
Electromagnetic induction is the process by which a changing magnetic field in a coil of wire induces a current in another coil. It was discovered by Michael Faraday and forms the working principle of generators and transformers.
7. What is the difference between a permanent magnet and an electromagnet?
A permanent magnet always retains its magnetism, while an electromagnet becomes magnetic only when an electric current flows through its coil. Electromagnets are usually made with a coil wound around a soft iron core.
8. What is the magnetic effect of an electric current?
The magnetic effect of an electric current refers to the ability of a current-carrying wire to produce a magnetic field around it. This effect is used in various devices such as electromagnets, electric bells, and relays.
9. Name two ways to increase the strength of an electromagnet.
The strength of an electromagnet can be increased by:
- Increasing the number of turns of the coil
- Increasing the current through the coil
- Using a soft iron core inside the coil
10. What are the uses of electromagnets?
Electromagnets are widely used in:
- Electric bells
- Motors and generators
- Cranes for lifting heavy scrap metal
- Telephones and loudspeakers
- Magnetic resonance imaging (MRI) machines
11. What is the Earth's magnetic field?
The Earth behaves like a giant magnet, with a magnetic field that extends into space. This field guides compass needles and protects the Earth from harmful solar radiation.
12. How do you test if an object is magnetic?
An object is tested for magnetic properties by bringing a magnet near it. If it is attracted strongly, it is considered magnetic. Materials like iron, cobalt, and nickel are typically magnetic.
