In addition, it will evaluate the shear modulus variations of the MREs due to continuously variable induced current and validate the performance of the carbonyl iron powder (CIP) orientation in each MRE specimen via SEM images.
Because of skin effect the electromagnetic field and induced currents are strongly attenuated, becoming null at a distance of some skin depth of surface.
The magnitude of the induced current and field is proportional to the strength of the applied magnetic field at any given moment.

With the help of the magnetic fields, the induced current density can be calculated by Eq.
3), induced current will circulate in the tube whose magnetic field opposes motion of the magnet by Lenz's law.
Approximately 63% of induced current and 87% of the generated heat is concentrated in the surface zone of heated body, designated by the term "penetration depth" (Rudnev, 2003).
If the nearby conductor is carrying its own current, then the induced current can alter the current distribution over the cross-section.
Antennas located near ground will experience signal attenuation for two main reasons: induced current in the antenna from nearby reflections and signal interference from reflected waves.

The induced current is directly proportional to the rate of change of the field in the active line.
Charge density of attrited particles was higher than that of intact ones, but induced current showed a reverse trend.
