Why MRI scans CAN make you dizzy: Magnetic fields disrupt fluid in
... 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 use the fluid's flow to detect motion. The discovery has implications for MRI-based brain research, say the scientists. They point out t ...

... Poles of Magnets If you suspend a bar magnet from its center by a piece of string, it will act as a compass. • The end that points northward is called the north-seeking pole. • The end that points southward is called the south-seeking pole. • More simply, these are called the north and south poles. ...

The Movement of Charged Particles in a Magnetic Field
... Some solar wind particles, however, do escape the earth’s magnetosphere and contribute to the Van Allen radiation belts. When these particles do enter the magnetic field, they go through three motions: • Spiral- the magnetic field changes the path of the particle. The particle, in its new path, is ...
