How work Pointer type Moving Coil Galvanometer?
The suspended coil galvanometers are very sensitive. They can measure the current of the order of 10-8 ampere. Hence these galvanometers have to be carefully…
Experiment: Torque experienced by a Current Loop in Uniform Magnetic Field
A uniform magnetic field exerts no net force on a current loop but it does exert a net torque. Torque (τ) is the twisting force…
Experiment: Force between two long Parallel Current Carrying Conductors
The force between two long parallel current-carrying conductors AB and CD are two straight very long parallel conductors placed in the air at a distance…
What is Ampere?
Ampere is defined as that constant current which when flowing through two parallel infinitely long straight conductors of negligible cross section and placed in air…

Explain Construction of Cyclotron
Construction of Cyclotron: A cyclotron is a device used to accelerate charged particles to high energies. It works on the principle that a charged particle…
Experiment: Force on a Current Carrying Conductor placed in Magnetic Field
Let consider a conductor PQ of length l and area of cross section A. The conductor is placed in a uniform magnetic field of induction…
Define and Describe on Cyclotron
Cyclotron is a device used to accelerate charged particles to high energies. It was devised by Lawrence. Principle Cyclotron works on the principle that a…
Define Direction of Force
