I've got a physics assignment at college. I've done all the questions except this one which is winding me up, I was wondering if you lovely geniuses (or genii) could help me.

I've been given diagram, with a magent on a pivot swinging over a coil, with 1000 turns. Its attached to a counter that counts each time the induced voltage exceeds 2.0mV. I have to calculate the rate of change of flux needed to induce this voltage (2mV) in the coil.

I realise the equation is Eind=change of flux/change in time
Or... Eind=BA/change in time. But I'm given no value for time, or Telsa, or area.

How can this be done?

Cheers in advance.

The answer is 42. You need a Death Magnetic to get it to work though. To set it up, you must divide by zero while playing Master of Puppets on the single coil.

Erm if they don't give any of those values....mission impossible really


Thats what I thought, but i doubt its a typo, our teacher would have pointed it out before giving us the assignment, he always does. Perhaps it cannot be done...



Frustrating.
