Factors that may affect a magnetic needle include proximity to other magnetic objects, electrical currents nearby, changes in temperature, and structural/material composition of the needle itself. Environmental factors like electromagnetic interference and large metal objects can also influence the behavior of a magnetic needle.

What happens to the compass when an aluminum bar is close?
The magnetic field of the compass may be slightly influenced by the presence of the aluminum bar, but aluminum itself is not magnetic so it won't affect the compass significantly. You would generally need a stronger magnetic field to noticeably affect the compass's needle.
How does a magnetized needle work?
A magnetized needle aligns itself with Earth's magnetic field, pointing towards the magnetic North Pole. This allows for a simple and reliable method of navigation, particularly in situations where other tools may not be available. The magnetized needle retains its orientation as long as it is not disturbed by other magnetic fields.
Which describes how a compass works?
. The south magnetic pole of the compass points to Earth's north magnetic pole.
What are the materials they used to make the magnetic compass?
The main materials used to make a magnetic compass are a magnetized needle, usually made of steel or iron, and a housing or casing to protect the needle. The casing may be made of materials like plastic, glass, or metal. Additionally, some compasses have a fluid-filled chamber to dampen the movement of the needle and improve accuracy.
Can a needle and a magnet become a compass?
answ2. A needle may easily be magnetized by gently stroking it in one direction. This can be converted into a compass which you may carefully float on the surface of water, where it will align itself with the lines of magnetic force at your location.You could speed up the process of magnetizing your needle by stroking it with one end of your magnet.In either case, if you consider the 'needle floating on surface tension' to be too difficult, you can pierce a small bit of cork or polystyrene foam with your needle, and float that.No

What factors may affect the strength of the magnetic field generated around a coil?
Number of loops and Battery voltage

How does a compass needle move when it is placed in a magnetic field?
A compass needle aligns itself with the magnetic field lines and points toward the magnetic north pole. The north-seeking end of the needle is attracted to the Earth's magnetic south pole, causing it to move and orient itself accordingly.

This allows for a simple and reliable method of navigation, particularly in situations where other tools may not be available.

What may cause a compass needle to point to a television rather than earths magnetic north pole?
The television or something in it must be generating a magnetic field.
Which describes how a compass works?
. The south magnetic pole of the compass points to Earth's north magnetic pole.
Does the needle in a compass always point south?
One side of the needle points north. This is the one that is usually considered, so you would say that the "needle points north", but of course, the other side points south. The part that points north is usually specially marked. The magnetic compass reacts to Earth's magnetic field, which doesn't exactly coincide with Earth's rotation, so there may be some deviation, that is, it may not point exactly north.
Name the factors that may affect osmosis?
There are at least 2 main factors that may affect osmosis. These 2 factors are amount of water and membrane permeability.
Does a compass needle always point directly northward in the absence of other nearby magnets or currents?
In the absence of interference from other magnetic fields or currents, a compass needle will align itself with the Earth's magnetic field and point towards the magnetic North Pole. However, it may not always point directly northward due to local magnetic anomalies or declination.
How will distinguish magnets from non magnetized magnetic materials?
You can use a device that detects magnetism. A compass needle may suffice.
