Question

a rectangular circuit measures 10cm x 25cm as shown in figure 7. it has a resistance of 5 ohms, presumed to be located as shown in the figure. there is initially no magnetic field in the area. the magnetic field everywhere is then increased at a constant rate to 2t out of the page over the course of 10 milliseconds, after which time the magnetic field stays at a constant 2t. how will the induced current in the circuit behave for the first 10 milliseconds (while the magnetic field is ramping up)?

Answer 1

So you can use the method and do the first bit but then work out the resisyence and calculate it to the millieseconds this will help very much
