Magnetic flux density
- force on a current carrying wire in a magnetic field when at right angles
- When perpendicular F=BIl
- Fleming's left hand rule:
- Magnetic flux density is also called field strength, B
- Tesla=Wb/m²
Moving charges in a magnetic field
- When the field is perpendicular to velocity, F=Bqv
- charged particles in a magnetic field are deflected in a circular path
- Effect used in cyclotrons
Magnetic flux and flux linkage
- Magnetic flux, φ = BA
- Flux linkage, Nφ = BAN
- Rectangular coil:
