- The device whose working principle is based on Helmholtz coils and in which uniform magnetic field is used is called as Helmholtz galvanometer.
- When a current carrying coils is suspended freely in earth's magetic field , its plane stays in east west direction
- Cyclotron frequency is also known as magnetic resonance frequency
- Cyclotron cannot accelerate electrons because they have very small mass
- Magnetic force does not work when the charged particle is displaced while electric force does work in displacing the charged particle
- Magnetic force is velocity dependend while electric force is independent of the state of rest or motion of the charged particle
- The value of magnetic field induction at a point on the center of seperaton of two linear parallel conductors carrying equal current in the same direction is zero.
