The force generated by a magnetic field B perpendicular to a wire carrying a current I is
where L is the length of the wire.
If we divide both sides for L, we get
where the ratio on the left is the force per meter of length, which is exactly what we want to find. So:
where L is the length of the wire.
If we divide both sides for L, we get
where the ratio on the left is the force per meter of length, which is exactly what we want to find. So:
