If the resistance of the coil is 4.6 , what is the magnitude of the induced current in the unit ampere, in the coil? QUESTION 3 A magnetic field makes an angle of 36° with the plane of a coil that has 147 turns and radius 2.4 cm. If the current in the coil is 4.4 0 A, what is the magnitude of the magnetic field, in tesla (T), that would produce a torque of 1.2 Nm on the coil? QUESTION 4 A circular coil of wire of radius 0.045 m and 42 turns is placed with its plane perpendicular to a 86 T magnetic field produced by an electromagnet, The currant to the electromagnet is then switched off causing the magnetic field to collapse to zero in a time of 0 3 5 What is the magnitude of the of generated in the coil whide the magnetic field is collapsing, in unit of volts?
