An emf (and therefore a current as well) can be induced in various process that involves a change in a magnetic flux without changing the line density of the flux 3. When a magnetic bar is moving toward a loop of wire, current will be induced in the wire 4. When a magnetic bar is static inside a loop of wire , current will be induced in the wire if the loop moves 5. When a magnetic bar is leaving a loop of wire, no current will be induced in the wire 6. The path of a charged particle in a magnetic field is always described the equation r = r = ae? cot b where r is the radius of the deflection 7. The earth's magnetic field interact with atmospheric charged particles_
