Magnetism (5/8) Flashcards
1
Q
Diamagnetic
A
Do not generate a net magnetic field and cannot be magnetized.
like water
2
Q
Paramagnets
A
Weakly attracted, unpaired electrons, material as a whole has no net dipole
3
Q
Ferromagnetic
A
Permanet magnets
4
Q
Dipole
A
The basic unit of magnetism
-north pole and south pole
they cannot exist in isolation
5
Q
Magnetic field
A
Strength is measured in Tesla
- only exert forces on moving charges
- moving charges generate magnetic fields
6
Q
Magnetic field strength equation
A
B=U_0I/2pi*r
7
Q
Magnetic force
A
F=qvB*sin_theta
-only exerts force on charged particles
8
Q
Magnetic field on a current-carrying wire
A
F=ILB*sin_theta
9
Q
Uniform magnetic field
A
R=mv/qB
