1. Introduction An electromagnet is a type of magnet in which the magnetic field is produced by electric current. An electric current flowing in a wire creates a magnetic field around the wire, due to Ampere's law (see drawing below). To concentrate the magnetic field, in an electromagnet the wire is wound into a coil with many turns of wire lying side by side. The magnetic field of all the turns of wire passes through the center of the coil, creating a strong magnetic field there.

4. Usage 4.1 With Arduino /* Turns on an Electromagnet on for one second, then off for one second, repeatedly. This example code is in the public domain. */ int Electromagnet = 0; int LED = 13; // the setup routine runs once when you press reset: void setup() { // initialize the digital pin as an output.
digitalWrite(Electromagnet, HIGH); // turn the Electromagnet on (HIGH is the voltage level) digitalWrite(LED, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(Electromagnet, LOW);// turn the Electromagnet off by making the voltage LOW 4.2 digitalWrite(LED, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second With Raspberry Pi 1. You should have got a raspberry pi and a grovepi or grovepi+. 2.
grovepi.digitalWrite(electromagnet,0) print "off" time.sleep(2) except KeyboardInterrupt: grovepi.digitalWrite(electromagnet,0) break except IOError: print "Error"} 5. Run the demo. sudo python grove_electromagnet.
