Lenz’s Law • The direction of an induced current is such that the magnetic field resulting from the induced current opposes the change in he field that caused the induced current. • When the N pole of a magnet is moved toward the left end of a coil, that end of the coil must become a N, causing ind ...

... The direction of the induced current (generated by changing magnetic flux) is such that it produces a magnetic field that opposes the change in original flux. E.g. If field increases with time the field produced by induced current will be opposite in direction to original external field (and vice ...

... Magnetic field lines are circles. They do not start or end at any point so this statement is false. Note on answer A: The dipole fields and thus the field lines of electric and magnetic dipoles are very similar. As a result they have similar expressions for the field strength as a function of dista ...

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.
