Magnetic field is produced by the magnet which will flow through any attractive item or even substance such as ferrofluid. Happy I could help:)
Answer:
Acceleration, 
Explanation:
Given that,
Speed of pilot, v = 475 m/s
Radius of the circle, r = 2310 m
If the pilot is moving in a circular path, it will experience a centripetal acceleration. It is given by the formula as :
So, the acceleration experienced by a pilot flying in a circle is 
. Hence, this is the required solution.
Answer:
• Bring another magnet wound with a copper wire, at the top of the fixed magnet. Here EMF will be generated by mutual induction
Explanation:
<h2>
Answer: It is the result of a mixture of radiation from many independent sources, such as stars and galaxies. </h2>
Microwave background radiation was accidentally discovered by Penzias and Wilson on 1964. This is a form of electromagnetic radiation that <u>is present in the </u><u>whole universe</u><u> and completely fills it (it is isotropic)</u>.
<h2>
It is the leftover radiation from the big bang.
</h2>
Its frequency belongs to the microwaves range and is one of the main demonstrations of the of the Big Bang theory model.
It is important to note the Big Bang occurred 400,000 years before the events related to the microwave cosmic radiation, this means the Big Bang occurred first.
