... Answer: Current carrying loops behave like bar magnets and both have their associated lines of field. This modifies the already existing earth’s magnetic field and a deflection results. Magnetic field has both direction and magnitude. Magnetic field lines emerge from N-pole and enter Spole. The magn ...

... where r is the distance from the center of sphere, and θ(x) = 1, if x > 0, and 0 otherwise. (a) Integrating the charge density over all space gives you the total charge Q. Thus, determine the constant b in terms of Q and R. (b) Using Gauss’s law find the electric field inside and outside the sphere. ...

... A B-field exerts a force on a moving charge. A current-carrying wire is full of moving charges, so a B-field exerts a force on the current-carrying wire. The force on a straight wire of length L, v v v carrying a current I, in a uniform magnetic field B, is given by F = I L ´ B , where we define a l ...

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.
