A changing magnetic field induces a circulating current in a wire loop.
My question is: Does the changing magnetic field also induce a current in a straight wire?
Ok, i solved it on my own.
Lets say that k = v1 / v2.
Then the radius of the circle is r = -dk -d / (k-1)
It works perfectly.:cool:
Thank for your help guys!
But this will not help me, will it werg22? There is no T since the velocities are instantaneous. I need to compute r. v1, v2 and d are known. Maybe I just don’t se it. Please give me an equation with r on one side of = and v1, v2 and d on the other.
I need to find the radius of a circle.
Consider two circles with a common center. The radius of circle #1 is r-d. The radius of circle #2 is r+d. The common center is called O.
A straight arm is rotating around O. Where the arm intersects the two circles we get two points of contact close...
