see if a magnet will stick to it
someone who knows stuff about magnets please improve this answer. I myself do not know because a magnet will not stick to a very weak magnet but it is still magnetic.
EDIT
why would you answer if you don't know the answer?
You stroke a bar magnet on the material and after a while it either becomes magnetic or not. unless its already magnetic which you would know straight away because it would stick to the bar magnet.
sorry if any of my answer doesnt make much sense ... hope i helped someone

Why is an electromagnet not use in compass?
An electromagnet in a compass would be influenced by Earth's magnetic field, making the compass less accurate. Additionally, the power source needed for the electromagnet would make the compass less reliable in various conditions, such as when the power source is unavailable or if it fails. Traditional compasses use a magnetized needle that aligns with Earth's magnetic field for consistent and reliable navigation.
What happened to the strength of the electromagnet when more turns of wire were used?
The strength of the electromagnet increases when more turns of wire are used because higher number of turns result in stronger magnetic fields produced by the current flowing through the wire. This strengthens the attraction of the electromagnet to magnetic materials.
List the factors on which the strength of the magnetic field of an electromagnet depends?
The strength of an electromagnets magnetic field depends on:The type of core metalThe ability of the wire to carry current (its material and thickness)The number of turns of the wiring around the coreThe voltage/current of the electricity going through the wire.
Does an electromagnet work without a nail?
Yes, an electromagnet can work without a nail. The core material affects the strength of the magnetic field produced, with a nail being a common choice due to its magnetic properties. Other core materials like iron or steel can also be used to create an electromagnet.
What does a dip compass do?
A compass does not point to the North Pole, it aligns itself with the lines of magnetic force at your location. In the Northern Hemisphere you are closer to the North Pole, so the strength from that direction is greater, and the compass "points north". In the Southern Hemisphere, similarly, the magnetic South Pole is closer, and the other end of the compass points to the south Pole. So far so good. But when you are close to either pole, the magnetic field dips into the earth - steeply at the Poles themselves. [Ordinary compasses are counterbalanced a little so the compass needle or card is approximately horizontal. The compass manufacturers divide the earth into five 'balance' zones.] So a dip compass is suspended between two pivots, and will indicate the steepness of the magnetic fields dip. It differs from an ordinary compass.
What device can be used to determine the direction of the magnetic field in the electromagnet?
A compass can be used to determine the direction of the magnetic field in an electromagnet. The needle of the compass will align along the direction of the magnetic field lines produced by the electromagnet.
What is the strength of an electromagnet proportional to?
The strength of an electromagnet is proportional to the number of turns in the coil, the amount of current flowing through the coil, and the magnetic permeability of the core material used in the electromagnet. Increasing any of these factors will increase the strength of the electromagnet.
What material do you need to find out the electromagnet's strength?
To find out the strength of an electromagnet, you would typically need a gaussmeter or teslameter to measure the magnetic field strength produced by the electromagnet. Additionally, the number of turns in the coil, the current flowing through the coil, and the core material used in the electromagnet will also impact its strength.
What are three factors that determine the strength of an electromagnet?
Three factors that determine the strength of an electromagnet are the number of turns in the coil, the material of the core used inside the coil, and the amount of current passing through the coil. Increasing these factors will generally increase the strength of the electromagnet.
Will the length of a wire affect strength of an electromagnet?
Yes, the length of a wire used in an electromagnet can affect its strength. A longer wire can provide more turns, increasing the magnetic field strength of the electromagnet. However, factors like the current flowing through the wire and the material of the wire also play important roles in determining the overall strength of the electromagnet.

What 3 factors affect the strength of an electromagnet?
The three main factors that affect the strength of an electromagnet are the current flowing through the coil, the number of turns in the coil, and the core material used in the electromagnet. Increasing any of these factors will typically result in a stronger magnetic field being produced by the electromagnet.
On what factors does the strength of an electroment depends?
The strength of electromagnet depends on the electric current flowing through the core because when the current is stopped, the core is no longer magnetized and the rate of change of flux linkage.
Witch r the factors that determine the strength of magnetic force an electromagnetic will have?
The factors that determine the strength of the magnetic force an electromagnet will have are the number of turns in the coil of wire, the current flowing through the wire, and the material of the core used in the electromagnet. Increasing these factors will generally increase the strength of the magnetic force produced by the electromagnet.
What happened to the strength of the electromagnet when more turns of wire were used?
The strength of the electromagnet increases when more turns of wire are used because higher number of turns result in stronger magnetic fields produced by the current flowing through the wire. This strengthens the attraction of the electromagnet to magnetic materials.

How strong can an electromagnet be?
An electromagnet can be very strong, with some industrial electromagnets capable of lifting thousands of pounds. The strength of an electromagnet depends on factors such as the number of coils of wire, the current running through the coils, the type of core material used, and the size and shape of the electromagnet.
