Ohm’s law — How a lifting magnet work

 

Industrial Lifting Magnets are very simple machines. They are nothing more than a string of wire wrapped around a magnetic core. This string of wire has resistance (ohms) that govern what current (amps) flows at a given voltage (volts). All DC magnets obey Ohm’s law. A magnet at room temperature, or ambient temperature, has the […]

How do you keep magnets safely within their designed operating range?

 

Simply by paying strict attention to the magnet’s duty cycle. Duty cycle is the time the magnet is in use. More specifically, duty cycle is the percentage of time a magnet is to receive its rated voltage in any 10-minute period. Most magnets are designed to operate at a 50 percent or 75 percent duty […]
