What types of magnets are produced by running current through a soft iron core?
When current is run through a soft iron core, an electromagnet is produced. This type of magnet can be turned on and off by controlling the flow of electricity. Soft iron cores are often used in electromagnets because they can quickly magnetize and demagnetize.
Are permanent magnets only attracted to other permanent magnets?
No, permanent magnets can also be attracted to ferromagnetic materials such as iron, cobalt, and nickel. This attraction is due to the alignment of magnetic domains within the materials, resulting in an attractive force between the permanent magnet and the ferromagnetic material.
Explain the difference between permanent and electromagnetic magnets?
In an electric magnet there is an ordinary metal used which when you run a current through it, induces a magnetic field, the permanent magnet (usually made of lodestone) contains particles which are already arranged in a manner that produces a magnetic field.
How an unmagnetized metal core is magnetized when it is inserted in a solenoid to make an electromagnet?
The solenoid will create a magnetic field inside the solenoid, running parallel to the length of the solenoid. This will happen with or without any metal core, when the current is running. If there is an iron metal core the solenoid's magnetic field will rotate the atoms in the iron in such a way as to reinforce the solenoid's field. The iron atoms are themselves tiny magnets oriented randomly. When alligned, the tiny magnets add to the original solenoid field to give a much stronger magnet.
What types of magnets are produced by running electrical currents through a soft iron core?
temporary magnets Incorrect, it's electromagnetic.
What types of magnets are produced by running electric current through a soft iron?
temporary magnets Incorrect, it's electromagnetic.
What types of magnets are produced by running electric current through a solf iron core?
Nothing is produced just by putting electric current through a soft iron core. It needs wire to be be wound around it in a certain fashion, then it may produce direct current.
Magnets that are made by wrapping wire around a metal rod and running electric current through the wire are called what kind of magnets?
Electromagnets.

Permanent magnets and electromagnets both hold their magnetism for a long period?
the answer is false Permanent magnets will hold their magnetism for a long period of time. Electromagnets will only remain magnetic as long as current is flowing through them.
Which magnetic material can retain permanent magnetization?
False permanent magnets can but electromagnets need a running current A+

How are magnets used to generate elecricty in a power station?
Yes, you can. You may recall that by running electricity through a coiled wire (solenoid) with an iron bar in the center, we can create an electromagnet. If we reverse this process and put a strong magnet through a solenoid, we can generate electricity. All you will have to do is move the magnet up and down in order to generate electricity.

When a car is running is the current ac or DC?
AC (alternating current) is produced in the the alternator. It is converted to DC (direct current) in the alternator by a configuration of diodes called a bridge rectifier. The remainder of the electrical system is DC.
