magnetic fields Flashcards
1
Q
magnetic flux density definition
A
the force on one meter of wire carrying a current of 1 amp at a right angle to the magnetic field
2
Q
equation for frequency (magnetic fields)
A
f=BQ/2pim
3
Q
equation for radius of magnetic field
A
r=mv/BQ
4
Q
why it is not possible for the magnetic field to alter the speed of a proton while it is in one of the D-shaped regions of a cyclotron
A
it is not possible because the force due to the magnetic field is perpendicular to the motion
this means only the direction of the particle will be changed, no work is done on the particle
5
Q
An electron follows a circular path when it is moving at right angles to…
A
a uniform magnetic field
