Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
Does the earths magnetic field has periodically reversed direction?
Yes. In historical times , clay pots have shown that the earth's magnetic field has reversed.
Will the polarity of the earths magnetic field change in 2012?
There is no reason to believe that the Earth's magnetic field will change any time soon... or, for that matter, that anything extraordinary is going to happen in 2012.
The force on an electron moving in a magnetic field will be the largest when its direction is?
perpendicular to the magnetic field direction
Earths magnetic field does not affect what?
Other planets
How does earths magnetic field change over time?
It changes over time through direction and strength. So therefore Magnetic North becomes Magnetic South.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
Does the earths magnetic field has periodically reversed direction?
Yes. In historical times , clay pots have shown that the earth's magnetic field has reversed.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire The magnetic field?
The magnetic field collapses to zero, then builds up again for the current in the opposite direction.
Earths magnetic field can make a magnet out of an iron bar by causing the magnetic domains to?
align in the same direction, creating a magnetic field within the iron bar. This alignment occurs due to the interaction between the Earth's magnetic field and the magnetic properties of the iron, resulting in the iron bar becoming magnetized.
Can earths magnetic field change directions?
sorry I forgot the answer. dummy!
Why do scientists think that earths' magnetic field has not always pointed north?
Every 100,000 years or so, the Earths magnetic field shifts direction. North becomes south, south becomes north.
What additional factor will be change if the direction of a current flow is change?
direction of magnetic field
What happens to the magnetic field of wire when you change the direction of a current of the wire?
In that case, the magnetic field will also be reverted.
What happens to magnetic field of a wire when you change the direction of the current in the wire?
Direction of the magnetic lines too would get changed
What happen to the magnetic field of a wire when change the direction of the current in the wire?
Direction of the magnetic lines too would get changed
Why does the earths magnetic field change over time?
The Earth's magnetic field changes over time because that is the way that God makes it.
