Forces on Moving Charges in Magnetic Fields Standards
... Students should understand the force experienced by a charged particle in a magnetic field, so they can: 1) Calculate the magnitude and direction of the force in terms of q, v, and B and explain why the magnetic force can perform no work. 2) Deduce the direction of a magnetic field from information ...

... Morley looked and looked, and decided it wasn’t there. How do waves travel??? Electricity and magnetism are “relative”: Whether charges move or not depends on which frame we use… This was how Einstein began thinking about his “theory of special relativity”… We’ll leave that theory for later…maybe. ...
