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.
How does a pulley decrease work?
A pulley decreases the amount of work needed to lift an object by distributing the force required over multiple ropes and pulleys. This reduces the amount of force needed by the person pulling the rope, making it easier to lift the object.
What is the Most suitable for making an electromagnet. a.copper b.iron c.lead d.tungsten?
b. Iron is the most suitable material for making an electromagnet due to its high magnetic permeability and ability to retain magnetization. Copper, lead, and tungsten are not as effective in creating a strong magnetic field.
What is a magnet made by electric current?
An electromagnet.
Why electromagnet is used for separating plastic bags?
An electromagnet can attract the metal, leaving the plastic behind.An electromagnet can attract the metal, leaving the plastic behind.An electromagnet can attract the metal, leaving the plastic behind.An electromagnet can attract the metal, leaving the plastic behind.
What is the difference between electromagnetism and electromagnet?
electromagnetism is the force an electromagnet is the object
What advantage does a electromagnet have over a bar magnet?
The electromagnet can be turned on and off depending on whether it's needed or not.
What does an electromagnet operator do to release metal attached to the electromagnet?
An electromagnet operator can release metal attached to the electromagnet by turning off the electric current flowing through the electromagnet coils. This de-energizes the electromagnet, causing the magnetic field to dissipate and the metal object to fall off.
Is making an electromagnet a physical process?
Yes
Where do the moving electrons come from when making an electromagnet?
When making an electromagnet, the moving electrons come from the flow of electric current through a wire or coil of wire.
Does making the core of an electromagnet larger make it weaker?
No, the electromagnet is not made weaker by making the core larger. It can be made weaker by decreasing its current and/or turns of coil.
What can a electromagnet not move?
An electromagnet is not able to move objects made of non-magnetic materials, such as plastic or wood. Additionally, if the object is too heavy or the magnet is not powerful enough, it may not be able to move the object.
How do you magnetize a sphere?
By making it an electromagnet. Include it in a circuit.
How do you magnetize sphere?
By making it an electromagnet. Include it in a circuit.
How does an electromagnet make the sounds you hear in headphones?
It needs more than an electromagnet. You have an electromagnet with an iron diaphragm in the magnetic field. When the audio current from the amp flows in the electromagnet, the diaphragm moves at the same frequency, making the sound that you hear.
Why does a crane use an electromagnet instead of a permanent magnet?
A crane uses an electromagnet because it allows for greater control over the magnetic force. The strength of an electromagnet can be adjusted by changing the amount of electric current flowing through it, making it more versatile for picking up different loads. Additionally, an electromagnet can be turned on and off as needed, which can improve safety and efficiency in crane operations.
Can a glass object be a electromagnet?
no it cant, because it will never have the abiliry to obtain magnetic properties
