c.the voltage is in the ratio of the resistances

All radiation comes from the nuclues. A neutrom changes in to a proton: n>p++e-

but isnt it IR= V
so if R decreases V decreases too bcuz they r propotional:S

jkiam11:
I have a question.

Why does cutting the magnetic fields with a wire generate a current?

astarmathsandphysics:
It generates a force on the elctronds in the wire according to lenzs law V=-d/dt
