Electrostatics Flashcards
1
Q
Fe
A
Fe= Kq1q2/r2
2
Q
Electric field (E)
A
Moves from + to -
- F=qE
- E= F/q= kQ/r2
3
Q
Electric potential energy
A
U= kQq/r
4
Q
Paramagnetic vs ferromagentic
A
Paramagnetic: weakly magnetized and have unpaired electrons
Ferromagnetic: strongly magnetized and have unpaired electrons
5
Q
Magnetic field for straight line
A
B= mew0I/2pier
6
Q
Magnetic force on amoving charge
A
F=qvBsin theta
7
Q
Force on electrical current conducting wire
A
F= ILBsin theta
