IB Physics Magnetic fields
/A tutorial sheet on topic D magnetic fields appears below.
- What produces a magnetic field?
- Two parallel wires carry equal currents in the same direction. Sketch a graph showing the magnetic field strength on a line through each wire perpendiculr to the wires.
- Sketch the magnetic field lines in the plane perpendicular to each wire.
- Three parallel wires carry equal currents I. The wires are at the vertces of an equilateral triangle of side d. Find the magnetic force per unit length acting on each wire.
