Why does the electric field inside a dielectric decrease when it is placed in an external electric field?
The net electric field inside a dielectric decreases due to polarization. The external electric field polarizes the dielectric and an electric field is produced due to this polarization. This internal electric field will be opposite to the external electric field and therefore the net electric field inside the dielectric will be less.
Which of the following are created by an arrangement of electric charge or a current?
for apex its: a quantum field, a gravitational field
Gets stronger as you get closer to an electric charge?
The electric field gets stronger as you get closer to an electric charge.
Why electric field lines cannot have sudden brakes in between them?
electric field lines represents electric field at that point but if it has break somewhere then it signifies the absence of electric field and it is not possible.....
Can gravitational be added to electric field to get the total field?
No. The sum of the gravitational field and the electric field is a useless concept.
Why do scientists believe that the inner core is the source of earths magnetic field?
because it has the hydro electric power to control the earths magnetic field
How is earths magnetic field similar to that of a bar magnet?
electric current in a solenoid coil
What do geologists think creates earths magnetic field?
Electric currents in Earth's molten outer core.
Is magnet useless or useful?
Useful - even before humans discovered compasses and "electric" motors, the Earth's magnetic field protected our atmosphere.
Where does the earths magnetic field originated from?
The Earth's magnetic field is generated by the the Earth's spin and the fact that it has molten iron in its core. When convecting molten metals spin they generate electric currents and with these a magnetic field.
How are the Earths magnetic field made?
It is made by the movement of the earths core and magma field
Why does the electric field inside a dielectric decrease when it is placed in an external electric field?
The net electric field inside a dielectric decreases due to polarization. The external electric field polarizes the dielectric and an electric field is produced due to this polarization. This internal electric field will be opposite to the external electric field and therefore the net electric field inside the dielectric will be less.
What is earths magnetic field called?
It is Earths' "Magnetosphere".
Which of the following are created by an arrangement of electric charge or a current?
for apex its: a quantum field, a gravitational field
Can an electric field exist without a magnetic field?
An electric field can exist even without the presence of a magnetic field. An example of this is a stationary electric field.
Is earths core a source of earths magnetic field?
Yes.
Gets stronger as you get closer to an electric charge?
The electric field gets stronger as you get closer to an electric charge.
