Induced Voltage Calculation for Stick in Magnetic Field B

[Petkovsky]

OK, so we have a stick 91cm long which is accelerated by 1m/s/s in a magnetic field B= 0.606T.

I need to find the induced voltage at time t = 288ms.

So U = B/V which is B/(a*t)

When i calculate i get 2 Volts which i think is too much. Plus the solution should be given in mV. Is this the correct result or I'm doing something wrong?

So U = B/V which is B/(a*t)

Uh, that equation is wrong. For one thing, it says a motionless stick (V=0) would generate an infinite amount of EMF!

What is the equation for EMF or U in terms of area and magnetic field?

Oh, sorry it's B * L * V, i missinterpreted l and /. Tnx, anyway it is a stupid equation the way i wrote it, I should have seen that.

No problem. If you're still stuck post again, but it sounds like you have it now.
