PPT-Chapter 21: Magnetism What is a magnet?

A magnet is anything that carries a static magnetic field around with it A magnet has a North and South pole Magnetic lines of flux make up the magnetic field and travel from North to South outside of the magnet.

Essential question:. Magnetic Field. While MRI is considered to be a safe imaging technique, it is not without hazards. The magnet field will attract many ferromagnetic metals in an uncontrolled fashion and cause them to fly towards the magnets bore and turning them into high velocity projectiles. The bore of the magnet is where the fringe field is strongest, as all the lines of force are constricted and their relative strengths heightened. Various objects can be considered projectiles.
