Does Rolling a Magnetic Core on a Magnet Affect Its Properties?

AI Thread Summary
Rolling a magnetic core on a magnet may influence its magnetic properties, particularly permeability and field strength, but the extent of this effect depends on several factors. The type of core material, such as ferrite, powdered iron, or laminated steel, plays a crucial role in determining the outcome. Additionally, the shape of the core, whether toroidal or otherwise, and its initial magnetization state are significant considerations. Clarifying these details is essential to understand the theoretical basis behind any changes in magnetic properties. Overall, the interaction between the core and the magnet during rolling could potentially enhance the core's magnetic characteristics, depending on the specific conditions.

Hi

Quick question related to magnetism

If I have a magnetic core and place that core onto a magnet, then roll the core on a flat surface ( whilst its still on the magnet), does that increase the permeability and magnetic field of that core ? If so, what is the theory behind that.

thank you in advance

Can you upload a sketch please (use the "Attach files" link below the Edit window).

Also, what shape magnetic core? Is it magnetized in some way? And what do you mean by "placing it on a magnet"?
 
What grade of material is the core made from?
Ferrite, powdered iron, or laminated steel?
Is it toroidal core?

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
