A200-turn rectangular coil having dimensions of 3.0 cm by 6.0 cm is placed in a uniform magnetic field of magnitude 0.76 t. (a) find the current in the coil if the maximum torque exerted on it by the magnetic field is 0.14 n · m. a (b) find the magnitude of the torque on the coil when the magnetic field makes an angle of 25° with the normal to the plane of the coil. n · m

With i really need the correct answer!
