Because they can then lift the steel easily without having to put chains and lifting gear onto it.
two bar magnets
Two factors that make gravity weaker or stronger are mass and distance. A more massive object has a greater force of gravity than a less massive object, and the closer two objects are increases the gravitational force between them.
An iron core and wire wound around it
An increase in the masses of the two objectsA shortening of the distance between the two objects.
there are two ways boy, first by increasing the number of colis 2. by using a stronger battery love, razor..
-- Increase the current (amperes) flowing through the coil of wire that surrounds the electromagnet. -- Increase the number of 'turns' of wire in the coil.

What are two ways to make a trapezoid
Phosphorus and calcium
A natural magnet is permanent - an electromagnet loses its power when it's switched off.
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.
Two ways that Hydrogen is used is by,using it as a compound to make gas for cars,and by using it as a compound to make water.H2O.
