Write expression for the magnetic field due to an infinitely-long current-carrying straight conductor.

The figure shows two semicircular current-loops of radii and . Find the magnitude and direction of the magnetic field at the common centre O.

An electron moving with velocity enters a magnetic field of at an angle of to the field. Calculate the force on the electron.

A current of is flowing upwards in a long vertical wire placed in a uniform horizontal northward magnetic field of . How much force and in what direction will the field exert on length of the wire?

Two long, parallel, straight wires and carrying-currents of and in the same direction are placed apart. Estimate the force on a section of wire .

A long horizontal rigidly supported wire carries a current of. Directly above it and parallel to it is a fine wire that carries a current of and weighs How far above the lower wire should the fine wire be kept to support it by magnetic repulsion?

Two very long, straight, parallel wires and carry currents of and respectively and are at a distance apart. If a third wire (length ) having a current of is placed between them, how much force will act on ? The direction of current in all the three wires is same.

A cyclotron accelerating protons has dees of radius and a radio-frequency supply of megacycles/ second at volt maximum value. Calculate the magnitude of the required magnetic field, the energy and velocity acquired by the protons. Take proton mass
