The detail that a force exists on a wire carrying a current in a magnetic field has an interesting application when we consider a current carrying loop. When the area vector is at right angles to the ...

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field ...

Figure 1: Cross-sectional view of a nanopillar spin-valve device. For an idealized model in which the free-layer magnetization behaves as a single domain, the Néel–Brown prediction for the activation ...

Key learning points Properties of magnets What are magnetic fields? Magnetic fields lines are invisible but they fill the space around a magnet where the magnetic forces work on magnetic materials, ...

Numerous test-and-measurement applications require a high-frequency magnetic field. Oftentimes, high field strength is needed. Examples of such applications include bio-medicine research on the effect ...
