Example 1 An electron travelling at 2.0 106 ms–1 enters a magnetic field of magnetic flux density 8.0mT at right-angles. Explain why the path described by the electron is a circle. Calculate the force acting on the electron due to the magnetic field. The force F acting on the electron is given by Fleming’s left-hand rule. This force is
Electromagnetic Force. induction …. The magnetic force on a moving charge is unlike other forces. It only acts when the charge is moving and is neither attractive nor repulsive.
Exercise 7.11. 7.1 A 10-MHz uniform plane wave is traveling in a nonmagnetic medium with m = m0 and er = 9. Find (a) the phase velocity, (b) the wavenumber, (c) the wavelength in the medium, and (d) the intrinsic impedance of the medium.

Force on a current-carrying conductor If a wire carrying an electric current passes through a magnetic field, with the field at right-angles to the wire, then the wire will experience a sideways force at right-angles both to the wire and to the magnetic field.
8. Explain the action of a step-down transformer. Your explanation should include reference to the parts played by the primary and secondary coils and the core of the transformer. You may be awarded a mark for the clarity of your answer.
