(Optional) Steel flat-head nail that could fit inside the straw, and a strong (rare earth) disk-magnet Create a coil Cut a 10cm length of straw. Wrap Sellotape around it a little way up from the ...

In general, a solenoid uses electromagnetic force to move a plunger, thereby converting electric energy into mechanical motion. (“Electromagnetic” means it’s only a magnet when electricity is applied.

Printed solenoids offer potential for high performance, tailored design, and on-the-spot fabrication. Why 3D-printed solenoids are needed and viable. How an MIT team devised an innovative approach to ...

Since humans first starting playing with electricity, we’ve proven ourselves pretty clever at finding ways to harness that power and turn it into motion. Electric motors of every type move the world, ...

When it is time to take your microcontroller project into the practical world, you often need something to create a linear motion directly. A push-pull solenoid can be a great choice for such ...

A proportional solenoid valve is an electromagnetic valve designed to respond to a variable power input to regulate the flow of liquid and/or gas proportionately. It is used to control the flow rate ...

This could not only reduce costs and eliminate manufacturing waste, but since this machine could be produced outside a factory, people with limited resources or those who live in remote areas may be ...

When I think of economizer circuits for solenoids and relays, I’m reminded of the phrase, “you can’t have your cake and eat it, too.” This phrase comes to mind because if you use a solenoid economizer ...
