For Alternating Magnetic Field?

Alternating magnetic fields (AMFs) are those fields whose amplitudes vary in time. The geomagnetic field

geomagnetic field
The Earth's field ranges between approximately 25,000 and 65,000 nT (0.25–0.65 G). By comparison, a strong refrigerator magnet has a field of about 10,000,000 nanoteslas (100 G).

(GMF) presents DC and alternating components. The sum of DC and alternating magnetic fields is called combined magnetic field (CMF).

What happens to the magnetic field in alternating current?

AC magnetic field is generated when an alternating current is passing through a coil. The AC current is a time-varying current and it is often a sine-wave. ... The magnetic field intensity or strength is depended on the alternating current. Therefore high-current is needed to produce high AC magnetic field.

What is magnetic field formula?

The equation for the magnetic field strength (magnitude) produced by a long straight current-carrying wire is: B=μ0I2πr. For a long straight wire where I is the current, r is the shortest distance to the wire, and the constant 0=4π10−7 T⋅m/A is the permeability of free space.
