How do you test whether a given rod is a magnet or not?
To start with we can suspend it freely by tying with a torsion less thread. If the axis of the rod always stands along north-south direction then we can conclude that the rod is a magnet. Moreover as we bring pins or nails then they will be attracted by the rod. This confirms that the rod is magnetic.
Would increasing the length of a rod in an electromagnet increase it's magnetism?
No, as in this case,the rod is the magnet,and the strength of a magnet does not depend on its size.
Will a positively charged glass rod be attracted to a magnet?
no.
How can you determine the magnet if you have one brass rod and another magnet in space?
Cut one in half, and see if the two bits attract or repel one another. If they do, you have cut the magnet. Otherwise the rod. If you are allowed other equipment, you don't need to cut anything. Make a coil, connect to a meter, and see which rod, when pushed in and out of the coil, induces a current.
How are electro magnet different from permanent magnet?
Electro magnets differs from permanent magnet because it requires electricity. A simple electro magnet consists of an iron rod wrapped in a coil of copper and when electricity flows through the copper, a magnetic field is formed.

Will rod magnet still become a magnet when it cut across into thin slices?
yes.when you slice a rod magnet it will still be considered as a magnet

Where is the magnet train at?
golden rod city
How do you make an iron rod into a magnet?
Same direction!
Will a positively charged glass rod be attracted to a magnet?
no.
Will a magnet stick to a carbon rod?
No, carbon itself is not magnetic.
How do you make a magnet by banging and hitting?
By striking the side of the end of a steel rod with a hammer you will make a weak magnet.
You are in a room where there are no objects except for two iron rods Only one of them is a magnet How can you identify the magnet?
Take a rod and touch with its end the middle of the second rod. If they move closer to one another, then you have a magnet in your hand. The real magnet has a magnetic field at its poles, but not in its center. So, as mentioned earlier, if you take the iron bar and touch its tip to the magnet's center the iron bar will not be attracted. This assumes that the magnet's poles are at its ends. There's no way you can identify which one is the magnet, 'cause there's no magnet in the room, only two iron rods. Tie your shirt or belt or sock etc. in the centre of rod and dangle it loosely and the magnet should point North quicker and more obvious than the non active rod
How does a motor run?
the north pole magnet and straight rod present in the moter .the current flow in the rod and rod rotate on the magnetic force.And the moter run.
How could a blind person identify iron rod and plastic rod?
By the apparent weight. By the sound made when the rod is struck. A magnet would differentiate between them.
