The magnetic equator is defined as the line around the earth where the magnetic field is horizontal, or parallel to the earth’s surface. It does not circle the earth as a smooth line like the geographic equator, but instead it meanders north and south, as shown.
What is the define of Equator?
An equator is an imaginary line around the middle of a planet or other celestial body. It is halfway between the North Pole and the South Pole, at 0 degrees latitude. An equator divides the planet into a Northern Hemisphere and a Southern Hemisphere.
What happens to the magnetic field vectors at the equator?
In the case of a dipole field, similar to the field observed in the near-Earth space, the field strength increases radially inward along the magnetic equator. … The effect is that a charged particle will always drift along a path that is tangent to the direction of increasing field strength.
Whats does magnetic mean?
1 : possessing an extraordinary power or ability to attract a magnetic personality. 2a : of or relating to a magnet or to magnetism. b : of, relating to, or characterized by the earth’s magnetism. c : magnetized or capable of being magnetized.
Where is the Earth’s magnetic field strongest?
What is an example of Equator?
The equator is defined as an imaginary line drawn on the Earth and spaced equally between the North and South Pole. An example of the equator is the latitude of 0°. A circle that divides a sphere or other surface into congruent parts. The celestial equator.
Is the equator hot or cold?
But why is the equator very hot and the poles very cold? There are several factors that influence the amount of sunshine received at various places on the earth. The major factor is that while the sun is overhead at the equator, it is at a rather slant angle at the poles.
Is Earth losing its magnetic field?
Over the last 200 years, the magnetic field has lost around 9% of its strength on a global average. A large region of reduced magnetic intensity has developed between Africa and South America and is known as the South Atlantic Anomaly.20 мая 2020 г.
Does the human body have a magnetic field?
In fact, every organ and cell in the human body has its own field. The magnetic field produces electrical currents that are weaker than you may first think. … This includes neurons, endocrine, and muscle cells – all called “excitable cells”. As all electricity does, this activity also creates a magnetic field.
How magnetic field is created?
Any current (movement of electrical charge) will create a magnetic field. Certain materials are capable of realigning the angular momentum of their electrons, and iron is one of them. When the angular momentum of electrons gets aligned, an external magnetic field is created.
What’s a magnetic personality?
You’ve probably heard of a person having a magnetic personality. If something or someone is magnetic, the object or person has an extraordinary power or ability to attract. We tend to attract people most like ourselves in our daily encounters.
What is another word for magnetic?

What are properties of magnet?
List of Properties of Magnet:
- Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel.
- Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other.
- Directive Property – A freely suspended magnet always points in a north-south direction.
Is Earth a magnet?
The crust of the Earth has some permanent magnetization, and the Earth’s core generates its own magnetic field, sustaining the main part of the field we measure at the surface. So we could say that the Earth is, therefore, a “magnet.”
What will happen if the Earth’s magnetic field flips?
During an excursion or a reversal, the magnetic field is considerably weakened and allows many more cosmic rays to reach the surface of the planet. These energetic particles from space can be damaging to life on Earth if too many reach the surface.
What happens if Earth’s magnetic field disappears?
But what would happen if Earth’s magnetic field disappeared tomorrow? A larger number of charged solar particles would bombard the planet, putting power grids and satellites on the fritz and increasing human exposure to higher levels of cancer-causing ultraviolet radiation.
