If a wire is moved near a magnet what happens

WebIntroduction Magnetic fields. Magnetic fields are vector quantities characterized by both strength and direction. The strength of a magnetic field is measured in units of tesla in the SI units, and in gauss in the cgs system of units. 10,000 gauss are equal to one tesla. Measurements of the Earth's magnetic field are often quoted in units of nanotesla (nT), … Web1 nov. 2024 · Let’s take a closer look at what happens when you wrap copper wire around a magnet. When you wrap copper wire around a magnet, you create a electromagnet. An electromagnet is a type of magnet that uses electricity to create a magnetic field. The electric current flowing through the wire creates a magnetic field around the wire. This …
