QoD (Lecture 9) > Heating with Magnetic eld Electric stove uses induction to heat up the pot. An alternating magnetic field, changing up and down, is created by the stove. The pot is made of conducting materials and a alternating current is induced in the pot. The resistance of the pot dissipate the electrical energy as heat. Consider the instance that the magnetic field is pointing up and decreasing at a rate of 0.05T/s. (a) Which direction is the induced current? TopView (clockwise/counter-clockwise) CINE\"- ' 7 . mm\" - . CDC lS-E (b) Simply assume the pot has a diameter of 20cm and ' * is made with 10000 wire loops and I has a total electrical resistance of R = 1.0. How much power (in W) is dissipated by resistance at that moment
