Jeff44 Posted May 10, 2018 Share Posted May 10, 2018 Hello everyone, I'm new to this so I'm not quite sure what I am doing, for an experiment I want to connect a Solenoid to a DC Power Supply, to control the strength of the magnet. Before I do is the any safety rules? If you can spare your time teaching me. I'd very much appreciate the time you have taken. Thank you - Jeff Link to comment Share on other sites More sharing options...
Bender Posted May 10, 2018 Share Posted May 10, 2018 Is the power supply 24V or lower? If not: don't use it until you know what you are doing. If yes: is it a variable or constant power supply? Hopefully it is variable, and in that case you should always start at 0 and gradually increase voltage or current when you turn it on and gradually decrease it to zero when turning it off. Abruptly cutting the current on a coil can cause extremely large voltages, sparks and stuff breaking. Lastly: don't put the magnet near creditcards or other magnetic cards or near electronic devices. 1 Link to comment Share on other sites More sharing options...
Jeff44 Posted May 11, 2018 Author Share Posted May 11, 2018 Yes, I will be using a 24V for the experiment, variable power supply is a must for my experiment. I was wondering what would happen if I cut the power off without turning down the voltage or current. Glad you told me. Thanks Bender. Link to comment Share on other sites More sharing options...
Bender Posted May 11, 2018 Share Posted May 11, 2018 You are welcome. Good luck. Care to share what the experiment is? Link to comment Share on other sites More sharing options...
