How Can Building an AC Electromagnet Affect Nearby Electrical Devices?

AI Thread Summary
Building an AC electromagnet can interfere with nearby electrical devices, particularly at 50/60Hz frequencies, affecting TV screens, computer monitors, and magnetic stripes on credit cards. At higher frequencies, such as 100kHz and above, interference may extend to AM radio reception. It's important to consider the strength and proximity of the electromagnet to minimize disruptions. Proper shielding and distance can help mitigate potential interference with household and neighboring electrical appliances. Understanding these effects is crucial for safe and effective experimentation.

Hi - I'm looking to build my own AC electromagnet for some personal science fun, however what I want to know is, at what point am I going to start interfering with the elctrical equipment in my house through the electric or magnetic (?) fields or worse start to affect my neighbours electrical applicances?? Many thanks

For 50/60Hz magnetic fields, mostly you have to worry about messing up your TV screen and computer monitors, and messing up magnetic stripes on your credit cards.

If you are going to work with frequencies in the 100kHz+ type range, then you might start to interfere with AM radio reception.
 

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...

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...
