To calculate we use the formula for a magnetic force in a current-carrying wire expressed as the product of the current, magnetic field and the length of the wire.
F = I x L x B
where F is the force on the wire, I is the current flowing on the wire, L is the length of the wire and B is the magnetic field.
F = 10.0 A x 1.2 m x 0.050 T
F = 0.60 N
