The polarity of the Earth's magnetic field reverses over time due to complex movements in the Earth's outer core. When the polarity changes, the North and South magnetic poles may also shift locations. This process is a natural phenomenon that has occurred multiple times in the Earth's history.

How do the north and south poles of a solenoid change with the direction of current flow?

The north and south poles of a solenoid change depending on the direction of the current flow. When the current flows in one direction, the north pole of the solenoid is at one end and the south pole is at the other end. If the current flows in the opposite direction, the poles switch places, with the south pole at the end where the north pole was and vice versa.


What do north and south poles of a solenoid change with?

The north and south poles of a solenoid change with the direction of electric current passing through the coil. When current flows in one direction, one end becomes the north pole and the other end becomes the south pole. Reversing the direction of current will reverse the polarity of the solenoid.


What is the strength and direction of the magnetic field outside of a solenoid?

The strength of the magnetic field outside of a solenoid is weak and the direction is similar to that of a bar magnet, flowing from the north pole to the south pole.


Can a solenoid suspended by a string be used as a compass?

A solenoid can be used as a compass when a DC current is going through it because when a current is going through the solenoid, the magnetic field lines are nearly uniform and perfectly parallel inside of it, giving it essentially a north pole and south pole.


Is the North Pole actually the South Pole?

No, the North Pole and South Pole are not the same. The North Pole is located at the top of the Earth, while the South Pole is at the bottom. They are opposite ends of the Earth's axis.

How many miles is it from the south pole to the north pole?

It takes about 12,450.5 miles from the north pole to the south pole or south pole to north pole.


What Location is at 90 Latitude?

The North Pole is at 90 North & the South Pole is at 90 South.


What lets the north pole and south pole of a solenoid be able to change poles?

The poles of the solenoid depend on the direction of the current through the coil. The current reverses if you just reverse the polarity of the voltage between the ends of the coil. Heck, if you energize the coil with AC, you can do that 120 times every second.


What you the latitude of the North pole and south pole?

The latitude at the north pole is 90° North. Thg elatitude at the south pole is 90° South.


Where is Arctic North pole or South pole?

the arctic is the north pole antarctica is the south pole :)


What are the characteristics of the north and south poles of both a magnet and the earth?

The North pole of a magnet or Earth attracts the South pole, while repelling the North pole. The South pole attracts the North pole and repels the South pole. For Earth, the North magnetic pole is located near the geographic North pole, and the South magnetic pole is near the geographic South pole.
