Why magnetic field lines emerge perpendicularly from the surface of permanent magnet?

This is somewhat to similar to the ejection of electrons right perpendicular to the surface of cathode. This is due to repulsion between the like charged electrons.
Same way magnetic lines of force never intersect and as they repel themselves they come out perpendicularly from the surface.

What do some scientists say about the relationship between sunspots and the Earth's temperature?
According to current theory, sunspots occur in pairs as magnetic disturbances in the convective plasma near the Sun's surface. Magnetic field lines emerge from one sunspot and re-enter at the other spot. Also, there are more sunspots during periods of increased magnetic activity. At that time more highly charged particles are emitted from the solar surface, and the Sun emits more UV and visible radiation. Direct measurements are uncertain.
Why B outstide a solenoid is non-zero?
B is non-zero outside a solenoid because magnetic field lines make closed loops so when they pass through the solenoid they also emerge from it thats why.
Why copper can't be magnetised?
Iron is a paramagnetic substance.so when a magnetic field is applied the molecules align itself in the direction of field.There may be other paramagnetic substances like iron.But diamagnetic substances are difficult to magnetise

0 mm. When you watch the tide go out and see rocks emerge, the ocean bottom is now at the ocean surface.
How do ring-tailed cats suvive in the desert?
Ring-tails emerge to hunt only at night when it is cooler. They also live in areas of the desert that are not far from permanent water.

What is the nail in an electromagnet?
The nail in an electromagnet is the core of the electromagnet. It is there to provide the magnetic lines of force a "highway" to get from one end of the coil to the other end through the middle of the coil. The magnetic lines of force "like" the nail because it is a ferromagnetic material. They can travel through it very easily - and they do! The nail also provides the "working end" of the electromagnet. The magnetic field lines emerge from the nail, and then act on what is there. If you are, say, doing a separation experiment removing steel tacks that are mixed in with small brass nails (brads), the tacks will stick to the end of the nail at the "working surface" or the pole of the electromagnet.
