GEOLOGY

Detailed explanation-1: -Nonmagnetic particles are magnetized by con tacting their surfaces with the magnetizing reagent in an aqueous medium and the coated magnetic particles couple with the nonmagnetic particles by adsorption.

Detailed explanation-2: -We know that only magnetic materials can be converted into magnet. One of the process of conversion of a magnetic material to a magnet is by magnetic induction.

Detailed explanation-3: -There are six basic types of magnetization: (1) diamagnetism, (2) paramagnetism, (3) ferromagnetism, (4) antiferromagnetism, (5) ferrimagnetism, and (6) superparamagnetism.

Detailed explanation-4: -The magnetization process A permanent magnet is magnetized by application of a strong outer magnetic field. This magnetic field forces the spins of the atomic electrons stepwise into its own direction. With increasing outer field the magnet will trace the new curve.

Detailed explanation-5: -You remagnetize a magnet by bringing it into contact with a strong magnet. So, if you have a weakened magnet, you must carefully bring it to contact with a strong neodymium magnet. This will make your weakened magnet regain its magnetic force.
