electromagnet
When a electric current is passed through an insulated wire that is coiled around an iron core, like a nail, an electromagnet is created.
Answer:
1. Where they multiply and stimulate formation of root nodules.
2. Enlargements of plant cells and bacteria in intimate association.
Answer:
9.773m/s2
Explanation:
Given,
h=8848m
The value of sea level is 9.08m/s2
So,
Let g′ be the acceleration due to the gravity on the Mount Everest.
g′=g(1−h2h)
=9.8(1−640000017696)
=9.8(1−0.00276)
9.8×0.99724
=9.773m/s2
Thus, the acceleration due to gravity on the top of Mount Everest is =9.773m/s2
Hope it helped!!!

Th answer is it could gain or loss magnetism.
Ferromagnetism is a kind of magnetism that is associated with cobalt, iron, and nickel and on some alloys or compounds containing one or more of the said elements, It also occurs in gadolinium, which is a rare-earth element. In comparison to other substances, ferromagnetic materials can be magnetized easily and in strong magnetic fields, the magnetization approaches a definite limit called stauration.
If an external field is applied and subsequently removed which does not return the magnetization to its original state or value it is called hysteresis. When heated to a certain temperature (Curie point), which is unique for each substance, ferromagnetic materials would somehow lose their magnetic properties and cease to be magnetic. Once they would cool down, their magnetism would return.
