They usually have two sets of coils. For a step-up transformer, there are greater number of turns in the secondary coil, while for a step-down transformer, there are less number of turns in the secondary coil compared to the primary coil.

The needle will rotate to point toward the opposite pole of a magnet. It helps in navigation by pointing toward the North magnetic pole and also useful in detecting small magnetic fields. -Jodelyn Eltagunde ]]> 2022-05-13 09:07:21 UTC https://padlet.com/workedrianpingol/v93o7s03212jwdih/wish/2182610000 https://padlet.com/workedrianpingol/v93o7s03212jwdih/wish/2183648436 Mag-Lev trains are trains that use magnets to hover above the ground. This is because there are huge magnets on the bottom side of the train and on the tracks that repel each other. Because of this, these trains can travel very fast - even up to 200mph

It is one of the basic materials needed in most mechanical equipments.

MRIs use powerful magnetic fields to generate a radar-like radio signal from inside the body, using the signal to create a clear, detailed picture of bones, organs and other tissue. An MRI magnet is very strong – thousands of times more powerful than common kitchen magnets.

The sound we hear is made up of these vibrations. Large magnets are commonly found within speakers, as a greater opposing magnetic field produces more vibrations.

Their role is to control the movements of the heads that read and write data. The data is on the platters and remains unchanged. Without the presence of a powerful magnet, the information remains on the hard drive.
