Magnetism is caused by current
Magnetic Field- 1. A magnetic field is created at all points in space surrounding a current
carrying wire
2. the magnetic field at each point is a vector
3. the magnetic field exerts forces on the magne

Standing Waves- are created from the superposition of traveling waves on top of each other
bouncing back and forth at the edges of the medium
Standing waves occur in well-defined patterns called modes, each with its own distinct

The Electric Potential
Work is only W=F(d) when the force is constant and parallel to the direction of motion
U + K = E (mech)
Change in potential energy U = -W
A constant force does work W= F (change in) r cos (theta)
