Magnetic Force Issues


1. A rectilinear conductor is traversed by an electric current of i = 2.0A when immersed in a uniform magnetic field of intensity B = 0.0002T, what is the magnetic force in a section of this conductor, in length l = 20cm in the following cases:

The)

For cases where the angle formed between the magnetic field and the current is 0, the force exerted by the field is 0, since:

But if 0 ° = 0, therefore, F = 0.

B)

For cases where the angle formed between the magnetic field and the current is straight (90 °), the force exerted is given by:

But sen90 ° = 1, then:

ç)

In the case where the angle formed between the magnetic field and the current is different from 0 °, 90 ° and their equivalents in the other quadrants, we use:
