A magnet can exert a force over a distance because of its magnetic field. The field extends around the magnet and interacts with other magnetic materials or objects at a distance, causing them to be attracted or repelled. This force is the result of the alignment of magnetic moments within the material.
The amount of force you exert remains the same, but the distance over which you exert the force can affect the work done. If you exert a force over a longer distance, you may do more work because the force acts over a greater distance. If the distance over which you exert the force is shorter, the work done may be less.
When you exert force on an object that causes it to move, it is called mechanical work. Work is defined as the product of the force applied to an object and the distance over which the force is applied in the direction of the force.
No, objects do not have to be touching each other to exert electrical force. The force between charged objects can be exerted through electric fields, which can act over a distance. This force diminishes with distance according to Coulomb's Law.
In an ideal machine, if you exert an input force over a greater distance than the output force, the input force will be smaller than the output force. This is because work input is equal to work output in an ideal machine, and work is calculated as force times distance. Therefore, if the input force acts over a greater distance, the output force must be larger to balance the work done.
If the mechanical advantage of a simple machine is increased, the distance the input force must be applied decreases in relation to the output force. This means that you can exert less input force over a longer distance to achieve a greater output force over a shorter distance.

A machine makes work easier by changing the amount of force you exert, the distance over which you exert your force, or the direction in which you exert your force.
It lightens the amount of force you have to exert to travel over a distance.
yes
A machine makes work easier by changing at least one of three factors. A machine may change the amount of force you exert, the distance over which you exert your force, or direction in which you exert your force.
They can both attract, or can repel, they can both act over a distance.

The distance is longer than the lift or the drop, but the force you need is less than the weight of the load.
