An electric motor has a square coil with 20 turns and an area of 150cm^2. the coil is free to rorate in uniform magnetic field of 300mT. If there is a DC current of 5.00A, passing through the coil: what is the maximum force on one side of the coil? and what is the maximum torque on the coil?

2. Relevant equations

3. The attempt at a solution

well i realised that there are 5 loops of this coil, i also figured that each turn is 7.5cm long. (150/4) = 37.5 (37.5/5) = 7.5cm, and im not sure where to go from here.
