Question

When a current carrying wire is placed in a magnetic field, a force exists on the wire, perpendicular to both the field and the wire. Is this true or false?

Answer 1

When a current carrying wire is placed in a magnetic field, a force exists on the wire. This force is known as the magnetic force.

The expression for the magnetic force is given as

$F=I(l\times B)$

Here I is the current

*Here B is the magnetic field

*Here l is the length of the wire

The magnetic force is both perpendicular to the field and the wire. Hence, the given statement is a true statement.
