Q1. In page 87  there are claims that magnets can heal people. Do you think this is possible?

 

Q2. If you wanted a motor to go without the magenet's pole switching, what would you do?

 

Q3. If you did the experiment on page 98 and the compass needle turned 45 degrees, can you guess how strong the magnetic force you made is?

 

A1 : I think it could be a bit true. In our red blood cells, there is iron.

Using the magnet, more blood might come to the injured area and provide

the necessary nutrition and oxygen to make the healing go faster.

 

A2 :  You could use half a magnet (the permanent one). But it would need

an initial speed to keep going this way.

 

A3 : If it turned 45 degree, it means that the magnetic force the earth effected

on the compass is equal to the magentic force the wire effected on the compass.
