Why magnet has only north and south pole?

The total effect is to make a huge magnetic field that points (approximately) in the northern direction. Taking these two ideas together, then, the Earth's magnetic field will cause the magnet to align north to south. That's why people named them the north and south poles.

The UNSC Naval Special Warfare Group has a group of supersoldiers called the Gray Team. Jai-006, Adriana-111, and Michael-120 are the most independent and individualistic of the Spartan-IIs. The United Nations Space Command has 7 more rows.

Can magnetic field intensity negative?

Yes, magnetic flux can be negative. It just depends on where the field is going. Say there is a sheet and magnetic field is going through it from front to the back, we can call the flux there as positive and negative when it's the other way round. What is E in F qE? In the physics equation, F=qE, where E is the electric field, q is the charge, and F is the force that the electric field exerts on this charge, does the charge, q, by itself, have a direction associa | Study.com.

Why do opposites attract magnets?

Like poles of a magnet repel each other. This is because when the two magnets of like poles are kept facing each other the lines of forces are in opposite directions. When the unlike poles of a bar magnet face each other the magnetic lines of force are in the same direction and hence unlike poles attract each other. Thereof, what happens to a magnet if it is cut in half? You can think of a magnet as a bundle of tiny magnets, called magnetic domains, that are jammed together. Each one reinforces the magnetic fields of the others. Each one has a tiny north and south pole. If you cut one in half, the newly cut faces will become the new north or south poles of the smaller pieces.

The Jovian planets are often referred to as giants. Jovian planets have thick atmospheres consisting of hydrogen, helium, methane, and ammonia. They have large amounts of ices, mostly water, ammonia, and methane.

Accordingly, can opposite magnets touch?

Opposite poles of a magnet attract each other, whereas like poles repel each other. However, when lined up with another north-seeking pole, the two magnets would push away from each other because their forces are not compatible.
