Electric and magnetic fields occur naturally and also come from human-made sources. Scientists and oversight agencies generally agree that low-frequency EMFs pose little danger to human health. Most ...

In day-to-day use, electromagnetic field (EMF) meters are used to diagnose problems with electrical wiring and power lines and to get readings on working appliances. On television, professional ghost ...

Electromagnetic fields are all around us — power lines and household appliances produce extremely low frequency EMFs, whereas cell phones and Wi-Fi devices emit radiofrequency EMFs. The general ...

An electromagnetic field (EMF) is an area of moving electrical charges. Some EMFs, especially those involving ionizing radiation, can be harmful. For most people, exposure to EMFs occurs on a daily ...

The concern over electromagnetic fields (EMFs) has grown significantly in a world increasingly dominated by electronic devices. With everything from smartphones and Wi-Fi routers to microwaves and ...

Let us begin this session by revisiting a nostalgic motor control IC—the AN6651—designed for rotating speed control of compact DC motors used in tape recorders, record players, and similar devices.

Typically, when we think about forming metal parts, we think about beating them with hammers, or squeezing them with big hydraulic presses. But what if magnets could do the squeezing? As it turns ...
