but the magnetic fields they produce are very weak. Oxides and alloys that have iron in them can also be magnetized easily, such as rust and steel. The more electrons in a metal that can be lined up, the stronger the magnetic field...
one at 10 tesla and one at 1 tesla. The 10 tesla magnet exerts a stronger magnetic field. A piece of magnetic material, placed equidistant from both magnets, would be attracted to the stronger of the two magnetic fields
How can a metal become a temporary magnet? What are two ways that magnetism is produced? Do permanent magnets lose their magnetism? What makes an object magnetic according to the Pauli exclusion principle? What is the sure test for magnetism? What are the properties of a magnetic field? Why...
Untestable: What makes a magnet attract things? Testable: Does temperature have an effect on a magnet's strength? Untestable: What happens when water expands as it freezes?What are three testable questions?Below are some example testable question formats: How does (IV) affect (DV) ? What ...
What makes a good lead magnet? You need to make your lead magnets worth your audience’s time. Here are some qualities of an effective lead magnet: 1. It delivers value. A lead magnet gets the attention of your audience — but the time frame for which you’ll hold their attention depen...

What does a changing magnetic field induce? How to make a magnetic field stronger. How can you create a uniform magnetic field using an electromagnet? What type of magnetism is characteristic of most materials? What is the domain theory of magnetism?
Ferrimagnetism: Like ferromagnets, ferrimagnetsretain magnetizationwhen removed from a magnetic field but neighboring pairs of electron spins point in opposite directions. The lattice arrangement of the material makes the magnetic moment pointing in one direction stronger than that pointing in the other ...
Their unique steel pot magnet design redirects the south pole flux lines around close to the edge of the north face of the ring and creates a stronger pull force to steel. Our fishing magnets work the same way and are made to attach directly to ferrous metal objects in rivers and lakes...
whereas electromagnetic movements (which depend on the flow of current through a wire to generate a magnetic field) are much lower in resistance. As we will see in greater detail to come, greater resistance (resulting in less current drawn from the circuit under test) makes for a better voltm...
