Magnetic field
The type of household magnet you are referring to is most likely a neodymium magnet, which is a strong magnet that can repel or attract other magnets. These magnets are commonly used in household items like refrigerator magnets. If one magnet is repelling another, it means they are oriented in such a way that their magnetic fields are pushing against each other, creating a repelling force.
a temporary magnet can be created by an electromagnet but it can also be created by any type of strong magnet
magnetism
An object that attracts material containing iron and always faces the same direction when moving freely is lodestone. ---- Nickel and cobalt are two other metals, in addition to iron, that display this type of magnetism. If you wish more information it is available on the wikipedia article entitled 'magnet'.
A neodymium magnet is a type of magnet that is unlikely to lose its magnetism. These magnets are made from a combination of neodymium, iron, and boron, which results in a very strong and durable magnet with high resistance to demagnetization.
The force of attraction or repulsion between two magnetic materials.
Ask the Mormans.
A magnet can exert a force on a non-magnetic object through magnetic induction. When a magnet is brought near a non-magnetic object, the object can become temporarily magnetized and experience an attractive or repulsive force depending on the orientation of the object and the magnet.
Iron filings will demonstrate the lines of magnetic force around a magnet.
A magnet exerts a magnetic force, which is the force of attraction or repulsion between magnets or magnetic materials. This force arises due to the alignment of the magnetic domains within the material, causing a magnetic field.

Tension
Iron filings are commonly used to demonstrate the lines of magnetic force around a magnet. When sprinkled around a magnet, the filings align themselves along the magnetic field lines, making the field visible.
The force exerted on the supported ropes of a hammock when you lie on it is tension. The ropes experience a tensile force pulling in opposite directions to support your weight and keep you suspended.
The force exerted on the support ropes of a hammock when you lie in it is a tension force. This force is along the length of the ropes and is balanced by the force of gravity acting on your body weight, keeping you suspended in the hammock.
Lodestone is an example of a natural magnet.
Whenever there is a certain type of force, one that fulfills certain conditions (called a "conservative force") - such as a magnetic field, an electric field, or a gravitational field - there is an associated potential energy.
