What is the force when the conductor are at an angle 45, Physics

Assignment Help:

Calculate the current needed in a 240 mm length of conductor of a d.c. motor when the conductor is situated at right-angles to the magnetic field of flux density 1.25T, if a force of 1.20N is to be exerted on the conductor.

A conductor carries a current of 70A at right-angles to a magnetic field having a flux density of 1.5T. If the length of the conductor in the field is 200mm measure the force acting on the conductor.

What is the force when the conductor and ?eld are at an angle of 45⁰?
