FAQs on Maharashtra Board Class 12 Solutions for Physics Chapter 10 Magnetic Fields Due to Electric Current - PDF
1. What is the direction followed by the magnetic field lines?
All the magnetic field lines flow from the South Pole to the North Pole inside a magnet but the opposite outside it.
2. What is a solenoid?
A conductor coiled on a non-conductor is called a solenoid. The conductor is insulated. It is used to make electromagnets and circuits.
3. What is a toroid?
A toroid is formed by coiling a conductor on a doughnut-shaped non-conductor. It is used in electric circuits when a large inductance is required.
4. What is the use of electric current-induced magnetic fields?
Magnetic fields induced due to electric current can be controlled in terms of intensity. They are used in making generators, sound devices, instruments, etc.
5. What is a conductor?
A material that allows the electrons to flow easily is called a conductor.
