Table 4.interaction between two permanent bar magnets what i did to the pair of magnets to cause interaction and observed the effect/s ( attracted or repeled

The two permanent magnets can interact with each other so that the two magnets are brought closer to the opposite poles so that they will attract each other

Magnets are objects that can attract other objects. Objects that are brought close to a magnet are attracted because they have a magnetic force

A magnetic field is a magnetic region that is still a magnetic force, so objects placed in a magnetic field will be attracted to a magnet

The strongest magnetic force is at the magnetic ends. This magnetic tip is called a magnetic pole consisting of the north pole and south pole

The magnetic north pole will point towards the north pole of the earth and the magnetic south pole will point towards the south pole of the earth.

Similar poles (north and south poles) will pull each other, while similar poles (north-north pole and south pole with the south) will repel each other

An iron or steel can be made into a magnet by rubbing, using an electric current or by induction.

Magnetic properties can be lost if magnets are heated or hit

Materials whose magnetic properties are easily lost are called temporary magnets such as iron and those that are hard to lose are called permanent magnets such as steel

The nature of materials that are exposed to or interact with magnets can give different responses. Some are drawn very strong, weak or even rejected. the nature of this material is classified into 3 namely ferromagnetic (easily drawn), paramagnetic (weakly drawn), and diamagnetic (slightly resisted)

So that the two permanent magnets can interact with each other, then the two magnets are brought closer to the opposite poles so that they will pull together

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
