Induction Flashcards
(7 cards)
1
Q
What is the voltage created from motional EMF
A
Deltav=velocity * length_conductor * magnetic field
assuming that the v and B vectors are perpendicular
2
Q
Whats the induced current?
A
VLb/R
3
Q
Pulling force of an induced current?
A
(vL^2B^2)/R
4
Q
Power applied on an induced current
A
(v^2L^2B^2)/R
5
Q
Magnetic flux equation
A
ABcostheta, A is area of loop of wire, B is magnetic field force and theta is angle between the normal and the b field
6
Q
What is magnetic flux in terms of?
A
1 weber=1 Wb = 1 T*m^2
7
Q
What is the right hand grip rule for solenoids
A
The direction of the magnetic field is given by the direction of your thumb if you use your right hand to grip the solenoid in the direction of current flow
