Answer:It is actually the South Magnetic pole
Explanation:The magnetic pole near earth's geographic north pole is actually the south magnetic pole. When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole.
Answer:
The Planck constant, or Planck's constant, is a fundamental physical constant denoted h, and is of fundamental importance in quantum mechanics. A photon's energy is equal to its frequency multiplied by the Planck constant. Due to mass–energy equivalence, the Planck constant also relates mass to frequency.
<h3>Theory:</h3>
Planck postulated that the energy of light is proportional to the frequency, and the constant that relates them is known as Planck's constant (h). His work led to Albert Einstein determining that light exists in discrete quanta of energy, or photons.
E = hf
Answer:
To reverse all types of defects.
Explanation:
In the magnetic particle inspection method the material which is used in testing will utilize the magnet which is ferromagnetic and it is high permeable and the retentivity of this magnet is low.
It is a technique which is not destructive and this technique is used for detecting the surface and the hollow part of ferromagnetic substance and will reverse all these defects.
Therefore, circular and longitudinal way of magnetization will reverse all the types of defect.
