The loop is immersed in an increasing magnetic field that is pointing out of the screen determines the direction of the induced current

Suppose the magnetic flux through a loop of wire increases by 25 T*m^2 in time At, and the induced current around the loop is 39 A. (The resistance of the wire is 2.5 ohm.) Determine the time At. (in s) OA: 0.100 OB: 0.117 OC: 0.137 OD: 0.160 OE: 0.187 OF: 0.219 OG: 0.256 OH: 0.300

An MRI technician moves his hand from a region of very low magnetic field strength into an MRI scanner’s 2.00 T field with his fingers pointing in the direction of the field. Find the average emf induced in his wedding ring, given its diameter is 2.20 cm and assuming it takes 0.250 s to move it into the field. Discuss whether this current would significantly change the temperature ofthe ring. Integrated ConceptsReferring to the situation in the above problem: (a) What current is induced in the ring if its resistance is 0.0100 ? (b) What average power is dissipated? (c) What magnetic field is induced at the center of the ring? (d) What is the direction of the induced magnetic field relative to the MRI’s field?

A closed loop is placed in a time varying magnetic field as shown in the figure in such a way that the loop is in an x-y plane and magnetic flux is through the loop along -z direction (into the page) and it is increasing magnitude with time. Then the direction of induced current 'T' in the loop is Select one: O Clock wise direction Anti-clock wise direction O No current will be induced
