Demonstrates how electricity can be produced from magnets through various experiments. It explains that electric currents can create magnetic effects, forming electromagnets that only work while ...

Electromagnets and transformers - AQA Electromagnetism is due to the magnetic fields around electric currents. The fields can cause forces with other nearby magnets which can be used to make ...

The ratio between the voltages in the coils of a transformer is the same as the ratio of the number of turns in the coils. \(\frac{\text{primary~voltage}}{\text{secondary~voltage}} = \frac{\text ...

In Nature, researchers report the discovery of a new type of fundamental magnetism, termed ‘altermagnetism’. Here, Juraj Krempasky, scientist at PSI and first author of the publication stands ...
