## Magnatic objects cannot be separated by various objects

Feb 21, 2020 Magnetism is a force that certain kinds of objects, which are called 'magnetic' objects, can exert on each other without physically touching. A magnetic object is surrounded by a magnetic 'field' that gets weaker as one moves further away from the object. A metal is said to be ferromagnetic if it can be magnetized (i.e.made into a magnet)

Sep 20, 2019 In layman’s terms, magnetism is a force that can attract or repel magnetic objects. Magnetic fields that permeate different mediums mediate this force. Magnetism is a property of certain materials by default. Some materials, though, can be magnetised or demagnetised depending on

The north pole and south pole of a magnet cannot be separated. Cutting one magnet in half makes two magnets, with two poles each. Earth’s magnetic field is around 1,000 times weaker than the typical bar magnet. Cranes use huge electromagnets to pick up scrap metal in junkyards. Electromagnets use electricity to generate their magnetic power

• Q & A: Gravity vs. Magnetism | Department of Physics

Jul 05, 2018 Unlike gravity, which occurs between any objects, magnetism depends on specific properties of objects. Magnetism can either pull the two objects together or push them apart, depending on which way the magnets point. Most importantly, it depends on what is going on with the electrons in the material, since each electron is like a tiny magnet itself

Crucial to the statement that electric current is the source of all magnetism is the fact that it is impossible to separate north and south magnetic poles. (This is far different from the case of positive and negative charges, which are easily separated.) A current loop always produces a magnetic dipole—that is, a magnetic field that acts like a north pole and south pole pair

Dec 07, 2014 Howard Curry. Dec 7, 2014. Magnetic fields (forces are caused by magnetic fields) cannot be blocked, no. That is, there is no such thing as a magnetic insulator. A major reason for this has to do with one of Maxwell's Equations: del dot B = 0. Which implies that there are no magnetic monopoles
