1.what are the two poles of a magnet?

2.what happened when you placed the magnet next to the copper?

3.what happened when you placed the magnet next to the iron?

4.what is the relationship between distance and magnetic attraction?

5.give three examples from your life of magnetic force.

1. This is called the north-seeking pole of the magnet, or simply the north pole. The opposite end is called the south pole. The needle of a compass is itself a magnet, and thus the north pole of the magnet always points north, except when it is near a strong magnet.

2. Nothing, copper isn't ferromagnetic so magnets aren't attracted to it.

3. The magnet is attracted to it and pulls it to it.

4. A material they make magnets out of and/or a material that magnets are attracted too. The name ferro implies that it is a material with iron in it.

5. Electric motors are only possible because of synchronized magnets chasing each other that causes the motion of the motor.

Hope This Helps c:

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
