itself in a definite cycle. It occurs whenever a body has a
stable equilibrium position and a restoring force that

SUMMARY
Magnetic forces: Magnetic interactions are fundamentally interactions between moving charged particles.
These interactionsSare described by the vector magnetic
field, denoted by B.
