If you want to maximize the magnetic force on a current in a conductor, how should you orient the current relative to the magnetic field?

Should place the current perpendicular to the magnetic field

Explanation:

The magnetic force exerted on a current-carrying wire is given by

where

I is the current in the wire

L is the length of the wire

B is the magnetic field

is the angle between the direction of the wire and the magnetic field

As we see from the formula, the magnetic force is maximum when

which means

So, when the current in the wire and the magnetic field are perpendicular to each other.

b.transmitters send radio waves, and receivers capture radio waves.
