Does the compass needle change irection if the flow of electricity in the wire near it is reversed?

yes indeed, in that case the current will be reversed thus, the magnetic field that coils on the wire will also be reversed(ex. from clockwise to counterclockwise and vice versa) you can understand this more by representing your right hand's thumb pointing as the direction of the current with the fingers closed, then the direction where the fingers are pointing will show how the magnetic field will coil through the wire.

Does the compass needle change direction if the flow of electricity in the wire near it is reversed?
true
How could you change the direction in which a compass needle points using a cell and a piece of wire?
The compass will react to magnetic fields, and magnetic fields are caused by currents. Therefore, holding a current-carrying wire close to the compass is enough to change the direction in which it points.The compass will react to magnetic fields, and magnetic fields are caused by currents.

How far do you need to keep a magnet from a compass?
The compass needle is magnetic so if you place a magnet near the compass, the needle will change direction either attracting or reppeling.
What are transformations that must occur to change your energy to electricity?
what is the tranformation of energy that must occur to change your energy to electricity
Why does a compass needle change direction when it is near a magnetic field?
Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.
Does the compass needle change direction if the flow of electricity in the wire near it is reversed?
true
Did reversing the direction of the electricity in the wire change the way compasses were affected?
Yes. If a current is reversed, the magnetic field is reversed as well.
What are the changes that can be reversed?
example of change can be reversed
What are example of a physical change that can be reversed and an example of a physical change that cannot be reversed?
an example of a physical change that can be reversed is like freezing water and letting melt back into water again
Is combustion a physical change?
NO its a chemical change for it can't be reversed
What is a the difference between a chemical and physical change?
A physical change can be reversed such as an ice cube melting. A chemical change, on the other hand, cannot be reversed such as burning wood.
Burning is what form of change?
it is a chemical change because it cannot be reversed
Can a physical change always be reversed?
No, not always. But mostly.
Can electricity and light bring reversible or irreversible change explain your answer?
Reversible: the light goes on, producing illumination; it goes off and it's as dark as it was. Irreversible: light causes a plant to grow which is not immediately reversed when the light is turned off
How did the compass change society?
the compass was made in the pioneer times it was used for helping them find their directions
How is sour milk a chemical change?
milk going sour is a chemical change because it can't be reversed. Most physical changes can be reversed for example snow melting is a physical change because it can freeze again.
Is an egg a chemical change?
Yes, it is, because it cannot be reversed.
