What is another word for materials?

Another word for material, if you are talking about food or liquid, would be ingredient. If you are talking about things that you will need to make or do something, then you can use the word supplies.


How many volts are needed to lift an electromagnet need to lift a car?

The amount of voltage needed to lift a car with an electromagnet depends on several factors. The size of the coil, as well as the amperage will need to be factored in to know how much voltage will be used.


What would you need to go to Jupiter?

you would need a space suit and supplies also a lot of space food and the most important a spacecraft.


Can you make an electromagnet with aluminum wire?

No. You should use a wire with the best electric conductivity (copper or silver) and wrap it around a (soft) iron core. The wire creates the magnetic field, the iron core concentrates it and turns into a magnet when a voltage is applied to the wire. Iron has rather poor conductivity and malleability so is not suited as the coil of an electromagnet.


Why are there more thumbtacks attached in electromagnet b as compared to electromagnet a?

I'm having a lot of trouble seeing the picture that goes along with this question in the book, so I'll have to take a wild guess based on no information. My guess is that electromagnet 'b' has more current flowing in its wire coil than electromagnet 'a' has. Another possibility is that the current through both coils is the same, but the coil of electromagnet 'b' is wound with more turns of wire than the coil of electromagnet 'a' is. It's just a guess. To be sure, I really need to see that picture.

How do you make a remote to electromagnet?

To make a remote-controlled electromagnet, you would need a remote control system, an electromagnet, and a power source. You can connect the power source to the electromagnet through a relay controlled by the remote system, allowing you to turn the electromagnet on and off wirelessly. This setup would enable you to control the magnetic force remotely.

What must you have for an electromagnet to work that you don't need for a regular magnet?

To make an electromagnet work, you need an electric current flowing through a coil of wire, which is not needed for a regular magnet.


Why would I need wine supplies?

If you are interested in making your own wine, then you'll need to stock up on some basic wine-making supplies. You'll need equipment for fermenting grapes, plus the right bottles and corks for starters. If you plan to make your own wine then you would need wine supplies. Als if you plan to transport wine you may need special supplies.


Metal core wire and what are needed to make an electromagnet?

To make an electromagnet, you would need a metal core wire (such as iron or steel) and a power source, such as a battery or electrical current. The metal core wire is wrapped around a core material and the electricity passing through the wire creates a magnetic field around the core, resulting in the electromagnet.


What are the three things we need to make an electromagnet?

To make an electromagnet, you need a magnetic core (such as iron), an insulated wire to create a coil around the core, and a source of electric current to flow through the wire and create a magnetic field.


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 item is necessary to make an electromagnet?

To make an electromagnet, you will need a coil of wire (usually copper), a power source (such as a battery), and a ferrous core (like an iron nail). When an electric current flows through the coil, it creates a magnetic field around the core, turning it into an electromagnet.


What two things are needed to make an electromagnet?

To make an electromagnet, you need a coil of wire and a source of electrical current. When the electrical current flows through the wire coil, it creates a magnetic field, turning the coil into a magnet.
