More currents, or more loops.
You can make an electromagnet stronger by increasing the number of loops in the coil or by passing more electricity through the coils or by chaging the core to a be replaced by a better conductor.
Answer you can increase the strength of an electromagnet by: 1) Increasing the current flow
2) Increasing the number of coils
3) Passing an 'iron core' through the coil of the electromagnet
You can increase the strength of an electromagnet by either increasing the number of turns, and/or by increasing the current, and/or by increasing the ferromagnetic density (permeability) of the core.
A long straight coil of wire can be used to generate a nearly uniform magnetic field similar to that of a bar magnet. Such coils, called solenoids, have an enormous number of practical applications. The field can be greatly strengthened by the addition of an iron core. Such cores are typical in electromagnets.
Holding a bar magnet with N to the left wrap the wire starting at the S end and go clockwise around the bar. Conventional current will flow from the right end of the wire around the coil out the left end.

if it's an electro magnet then you can add more coils to it. i don't know about permanent magnets
You can make it stronger by using a copper wire and a batteries.1st, make a circuit then, attach the magnet to the positive side of the batteries.
put it in the freezer over night
stroking it
-- Increase the current (amperes) flowing through the coil of wire that surrounds the electromagnet. -- Increase the number of 'turns' of wire in the coil.
One way to increase the strength of a copper electromagnet is by adding another coil. Another way is by wrapping the copper coil around a nail made of iron.Adding more loops to the wireWrapping the copper wire around an iron nailIncreasing the current
Electromagnet
yes it is easily controlled.

As current increases, the electromagnet strength will increase.

Yes
Yes
using a stronger ferromagnetic material for the core. :)
Add a battery
For a simple copper wire around iron nail electromagnet, increasing the number of rounds the copper wire makes around the nail will increase the electromagnet's strength. Also, increasing the voltage applied(adding a battery) will increase the magnetic field.
-- Use greater length of wire. -- Wind it into more turns around the coil. -- Decrease the diameter of the coil. -- Increase the electrical current through the coil. Each of these actions will increase the strength of the electromagnet.
No, as in this case,the rod is the magnet,and the strength of a magnet does not depend on its size.
