-- Increase the current (amperes) flowing through the coil of wire
that surrounds the electromagnet.
-- Increase the number of 'turns' of wire in the coil.
The two ways to increase the strength of a magnetic field of an electromagnet include increasing the current and increasing the number of wire revolutions around the iron bar. Having fewer windings weakens the electromagnetic strength.
More currents, or more loops.
Increase the pressure and temperature by burying them; or heat them with an igneous intrusion.
Weathering is the breaking down of rocks, soil andminerals as well as artificial materials through contact with the Earth's atmosphere, biota and waters. Weathering occurs in situ, or "with no movement", and thus should not be confused with erosion, which involves the movement of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity.
The earth is an electromagnet. It has a north pole and a south pole. Apex: A magnet always has two poles, earth is a elecrtomagnet

Add another magnet. If an electromagnet increase the windings and/or the power applied. Raise the voltage applied and you will raise the magnetic flux.
strength and direction
U can increase and decrease it
More currents, or more loops.
1. Increase the strength of the magnetic field. (More field lines to be cut by wire, therefore more voltage induced) 2. Move the magnet - or the wire - more quickly. (More field lines cut per second, therefore more voltage induced) 3. More coils in wire. (A single straight wire moved in a magnetic field will cut the lines once, but a coil of wire will cut the lines twice. More coils, more cutting, more induced voltage).
No.
-- Decrease its mass. -- Increase the net force acting on it.
Agitation and heat.
Two ways to increase oxygen pick up by mammals would include breathing more deeply and breathing more rapidly
There's only one way and that is to increase the force acting on it.
Okay 2 ways for the friction to increase is speed and non lubricant
