A black hole can have an electric charge if it swallows electrically charged objects, but no objects that we know of have magnetic charge. Magnets always have both a north pole and a south pole; there is no evidence that one can exist alone. A lone north or south pole would be called a magnetic monopole, and would have magnetic charge. If we discovered a magnetic monopole and fed it to a black hole then the black hole would gain the magnetic charge.

∙ 14y agoOne of the solutions to the Einstein field equations is called the Kerr-Newman metric, which describes a black hole which is both electrically charged and has angular momentum... and a charged object which has angular momentum generates a magnetic field.

What do you mean when you say Black holes have no hair?
It means they have no magnetic fields.
What is the South Pole's magnetic charge?
The location we call 'Magnetic South' is a magnetic north pole. We do not use the term 'charge' to refer to magnetic poles.
Does the gravity affect the magnetic force lines by space distortion?
Magnetic lines of force follow space. If space is distorted by the presence of a large gravitational field, the magnetic lines will be distorted as well. Other than near black holes, this effect is negligible.
What does it mean to say black holes have no hair?
Saying that black holes have "no hair" means that they lack any detailed or distinguishing features. It is a metaphorical way of saying that all black holes, regardless of their initial conditions, will eventually settle into a state characterized by only three properties: mass, charge, and angular momentum. All other information about the matter that formed the black hole is lost.
Can black holes dies?
Black holes do not die but they can evaporate.
What do you mean when you say Black holes have no hair?
It means they have no magnetic fields.
Do black holes get electricety?
black holes swallow all energy and matter around them, including electricity
Can a battery have a magnetic charge?
No the battery don't have a magnetic charge.
How are black holes classified?
They can be classified according to whether they rotate or not; their electrical charge; but especially their mass.
Are there other forces than gravity in black holes?
A black hole may have an electrical charge. This is assumed to be usually insignificant, compared to its gravity.
What is the South Pole's magnetic charge?
The location we call 'Magnetic South' is a magnetic north pole. We do not use the term 'charge' to refer to magnetic poles.
Can a moving electric charge create a magnetic field?
Yes. A spinning charge will create a magnetic field as will a moving charge.
Does the gravity affect the magnetic force lines by space distortion?
Magnetic lines of force follow space. If space is distorted by the presence of a large gravitational field, the magnetic lines will be distorted as well. Other than near black holes, this effect is negligible.
What were black holes before they turned into black holes?
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
Why is electromagnetic activity called that?
Because the magnetic charge makes a electicric charge ing the magnetic field.

How many different types of black holes are there?
There are four types of black holes. In size and physical construct.Size:Supermassive: These have a mass of between 105 -> 109 million Suns yet have a diameter of 0.001 -> 10 AU (an AU is approximately 150 million kilometers). It is believed that most, if not all galaxies have a supermassive black hole in their centre.Intermediate mass black hole. These have a mass of around 103 million Suns yet have a diameter of 103 kilometers (About the radius of Earth)Stellar-mass. These have a mass of about 10 million Suns but are only around 30 kilometers in diameter.Micro black hole. These have the mass of a million Moons but are tiny, up to 0.1 mm in diameter.Physical construct:Black holes with no electrical charge, and without rotationBlack holes with no electrical charge, and with rotationBlack holes with an electrical charge, and without rotationBlack holes with an electrical charge, and with rotation.See related links for more information
