Why the negative sign?
Because emf tends to OPPOSE
the flux change.
(This is Lenzs contribution.)
Change magnitude of B
Change area of coil
Change orientation of coil WRT B
magnetic fields and forces
How can we create a
v = E/B
Only particles with this speed can pass through
Speed can be controlled.
Will it continue to rotate forever?
This is the basis for the DC mot
Potential due to a positive point charge located at the origin:
Charged spherical shell of radius 1.0 m:
electric charge and electric field
How does an object become
For a charged ring, find the
maximum field strength along the
axis of symmetry of the ring.
