Question
If anyone can help me with these, my book doesnt explain and notes didnt cover this.
1.)In terms of angle, when is the force on a current-carrying wire in a magnetic field the strongest? When is is zero?
2. How are E and B fields in electromagnetic waves oriented?
3. List the following electromagnetic waves from longest to shortest wavelenght: microwaves, Xrays, infrared, orange light, ultraviolet, television, radio waves, blue light
4. Will an Electron at rest move in a magentic field? Why or Why not?
THANK YOU
Explanation / Answer
1)
when current passes perpndicular to the magnetic field F is maximum
when current passes parallel or anti parallel to the magnetic field F is miniumum(zero).
2) perpendicular to each other and perpendicular to propogation of wave.
3) radio > microwave > infrared > orange light > blue light > ulta voilet > X-ray
4) no.
F = q*v*B*sin(theta)
when v = 0, F = 0
