Magnetic Field Iron

Why is Earth Magnetized and Venus Not?

Based on its density alone, Venus must have an iron-rich core that's at least partly molten — so why does it lack the kind of global magnetic field that Earth has? To generate a field, the liquid core needs to be in motion, and for a long time theorists suspected that the planet's glacially slow 243-day spin was inhibiting the necessary ...

How to Use Iron Filings to See Magnetic Field

Magnetic Field Iron Filings Experiment—Conclusion. From the experiment results, we can conclude that the North Pole of one magnet repels the North Pole of the other. In the same way, the South Pole of one magnet repels the South Pole of another magnet. But the North Pole of one magnet attracts the South Pole of another magnet and vice versa.

21.1: Magnetism and Magnetic Fields

Earth's magnetic field is mostly caused by electric currents in the liquid outer core, which is composed of highly conductive molten iron. A magnetic field is generated by a feedback loop: Current loops generate magnetic fields (Ampère's law); a changing magnetic field generates an electric field (Faraday's law); and the electric and ...

magnetic fields

If iron is dissolved in water (polar liquid), it will be in the form of ions. If we apply uniform magnetic field these ions will gyrate around this magnetic field and will do nothing but if we apply a non uniform magnetic field and the non uniformity is perpendicular to the direction of magnetic lines the ions will slowly drift from high field region to low field region (regardless of …

What is the force on an iron object due to a magnetic field?

Say there is a solenoid that creates a constant magnetic field in the space around it. An iron ball bearing is placed at one end of the solenoid where the field lines spread out. What would be the formula for the force on the ball bearing? I imagine it has something to do with the iron being assumed to be a collection of dipoles?

Y es, you can yourself draw the field lines of a bar magnet. Activity 13.3 n Take a small compass and a bar magnet.

Create a homogeneous magnetic field with iron yoke

To create a magnetic field that is as homogeneous as possible, it is recommended to place two large magnets close to each other and to connect the back sides with an iron yoke. There will be a reasonably homogeneous field in the gap between the magnets. The smaller the gap and the larger the magnets, the more homogeneous the field will be.
