Magnetism and Magnetic Fields Boundless Physics

Magnetism and Magnetic Fields. Earth's magnetic field is generated by a feedback loop in the liquid outer core Current loops generate magnetic fields; a changing magnetic field generates an electric field; and the electric and magnetic fields exert a force on the charges that are flowing in currents (the Lorentz force). by comparison

Magnetic tape is inexpensive and budget friendly. Disadvantages. Special equipment must be purchased and set up for recording and storing data. The data can only be read on the special equipment. If the data is stored near a strong magnetic field or a large speaker, the tape can be damaged. Magnetic tape has a lifespan of 15 years.

Inductor Core Material The Heart of an Inductor Power

An inductor's magnetic core is made of specially formed material with "soft" magnetic properties. Although physically hard, a magnetic core is said to be "soft" when it doesn't retain significant magnetism. A magnetic core is usually surrounded by carefully arranged windings of wire. The combination of magnetic core and windings results

Comparison of Axial Flux Permanent Magnet Synchronous

This paper presents a comparison of axial flux permanent magnet machines (AFPMs) with an electrical steel core and that with a soft magnetic composite (SMC) core. SMCs have several advantages such as low core loss and low eddy current loss. However, compared with electrical steel, SMCs have poor magnetic properties such as low flux density saturation and unsaturated relative permeability.
