Week 8 - Magnetic Field and Magnetic Forces
... c) A student claims that if lightning strikes a metal flag pole, the force exerted by the earths magnetic field on the current flowing trough the pole can be enough to bend it. Typical lightning currents are of the order of 104 to 105 amperes. Is the student’s opinion justified? d) A loudspeaker sho ...

Why MRI scans CAN make you dizzy: Magnetic fields disrupt fluid in
... MRI vertigo is caused by interplay between the magnetic field and the salty fluid that fills labyrinth canals, the scientists believe. The magnetic field is thought to push on the current of electrically charged particles circulating within the tubes. This in turn exerts a force on the cells which u ...

Magnetic monopole
A magnetic monopole is a hypothetical elementary particle in particle physics that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). In more technical terms, a magnetic monopole would have a net ""magnetic charge"". Modern interest in the concept stems from particle theories, notably the grand unified and superstring theories, which predict their existence.Magnetism in bar magnets and electromagnets does not arise from magnetic monopoles. There is no conclusive experimental evidence that magnetic monopoles exist at all in our universe.Some condensed matter systems contain effective (non-isolated) magnetic monopole quasi-particles, or contain phenomena that are mathematically analogous to magnetic monopoles.
