Letter: Up-to-date magnetic units would be so much clearer. Published 22 May 2019. From Keith Atkin, Sheffield, UK ... The tesla is the modern SI unit of magnetic flux density.

Earlier, the power of a magnet was only measured in units of gauss. Gauss defines the number of lines of magnetic (flux density) per square centimetre emitted from the surface of the magnet.

A Chinese research team has set a new record for a flat-top pulsed magnetic field (FTPMF) with a whopping 71.36 tesla, ...

Researchers from the Chinese Academy of Sciences set a new record on August 12, 2022, of 45.22 teslas (T, the standard unit of magnetic flux density) using a hybrid magnet.

While the researchers were hoping that the field would reach 700 teslas, the unit used to measure magnetic flux density or informally, magnetic field strength. Instead, the field reached 1,200 teslas.

In some maths questions you will be required to give the units. ... Calculate the magnetic flux density. Gravitational field strength = 9.8 N / kg [5 marks] Show answer Hide answer.
