Embibe Experts Solutions for Chapter: Moving Charges and Magnetism, Exercise 1: Nagaland Board-2018

State Biot-Savart law. Use this law to obtain the expression for the magnetic field on the axis of a circular current loop.

With the help of a diagram, explain the principle and working of a cyclotron. Show that cyclotron frequency does not depend on the speed of the particles.

A strong magnetic field is applied on a stationary electron. Then the electron

How does cyclotron increase the energy of charged particles?

State and prove Ampere’s circuital law.

Define Lorentz force. Derive an expression for the force on a current carrying conductor placed inside a uniform magnetic field.
