WebApr 2, 2007 · Magnetic resonance imaging (MRI) is an imaging technique used in radiology that uses strong magnetic fields, magnetic field gradients and radio waves to generate … WebFirstly you can heat the iron until the thermal vibration of the atoms overcomes their tendancy to line up. This is called the Curie temperature, and above this temperature the net magnetism disappears. The other way is to take your piece of iron and start remagnetising it in the opposite direction.

WebKey terms. A field models what an object would experience related to a force at a given point in space. A magnetic field is a field explaining the magnetic influence on an object in space. A electric field is a field defined by the magnitude of the electric force at any given point in space. Current is the rate of charge moving past a region. WebIf you try to put two magnets together with the same poles pointing towards one another, the magnets will push away from each other. We say they repel each other. Different poles …
WebDec 10, 2024 · Magnetic fields indeed simply combine via superposition - like in waves. The potential energy of magnetism is V = − 1 2 μ ⋅ B where μ is the magnetic moment (vector) of the, in this case, conductor and B is the magnetic field strength (vector) and the dot represents the scalar product. WebHow do magnets work? In a bar magnet, magnetism is strongest at the ends, or poles. The north pole always points north. The south pole always points south. Magnets attract other magnets. Unlike poles attract each other. The north pole of one magnet attracts the south pole of another magnet. But poles that are alike repel, or push away from ...
