# Magnetic force of a magnetic field around a wire

Suppose we have a magnetic field around a wire because there goes a current through the wire. Suppose there are not any magnets near. Is it ture that there is then also a magnetic force?

If so, is it true that we may deduce the direction of $B$ using the right-hand rule and the direction of the magnetic force $F$ using the left-hand rule?

• What do you mean "magnetic force"? You mean that, absent external magnetic fields, the wire experiences a force due to the magnetic field it is generating? Dec 24 '15 at 14:59
