the magnetic field lines become almost parallel which indicates that this part of the coil has a uniformmagnetic field. In other words, we can say that at the centre of the circular loop, magnetic field lines become straight lines

Demagnetized Magnetized S N A longitudinal magnetic field has magnetic lines of force that run parallel to the long axis of the part. A circular magnetic field has magnetic lines of force that run circumferentially around the perimeter of a part. Being able to magnetize the part in two ...
The fringing field lines created by the recording head in the magnetic media. Sign in to download full-size image Figure 37.7. Typical MHL for a recording head. Prior to the recording process, the magnetic media is demagnetized. For this reason, a supplementary erasing head was introduced in...
The Electric and Magnetic Field Instrument and Integrated Science (EMFISIS) investigation on the NASA Radiation Belt Storm Probes (now named the Van Allen Probes) mission provides key wave and very low frequency magnetic field measurements to understand radiation belt acceleration, loss, and transport...
Flowing an electrical current through a coil of wire around the part or through a central conductor running near the part. Direction of the Magnetic Field Two general types of magnetic fields (longitudinal and circular) may be established within the specimen. The type of magnetic field established...
Very most of the field energy is allocated closely around an air coil; it does not extend very far into space. In general, the total magnetic energy of an inductor L is also known as(5)EM=12LI2and when comparing Eqs. (5), (4), the inductance L of a coil, in an even more ...
However, when the MFEH is close to the rail track, the magnetic field generated by the MFEH produces circular eddy currents in the rail track, leading to an energy loss. This energy loss is reflected as the increased internal resistance of the coil, which can be expressed as(7)Rc=Rw+...
