Answer:
C direction
Explanation:
Reversing the direction of the flow of electric current in a wire coil reverses an electromagnet's north and south poles.
Every time the north and south poles is exchanged, the direction of flow of electric current in a w ire reverses.
- An electromagnet is a form of magnet in which the magnetic effect is produced by the movement of electric current in wire.
- A coil of wire wound round and connected to an electric source will produce an electromagnet.
- When we change the direction of flow of the current the polarity of the poles will also change.
Explanation:
Gravity
Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996).
A sound wave is the answer
Answer:
Conduction, Convection and Radiation
Explanation:
Hope this helps!
The North Magnetic Pole is the point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downwards (in other words, if a magnetic compass needle is allowed to rotate about a horizontal axis, it will point straight down). There is only one location where this occurs, near (but distinct from) the Geographic North Pole and the Geomagnetic North Pole. So yes true
