All,

I'm looking to purchase a small electromagnet (no longer than 1 foot) that would go around a ~0.375" tube and hold ferrous balls in the tube in addition about ~15 vertical feet of additional balls above the emagnet. The total weight would only be about 4 lbs. Anyone know where I could purchase somehing like this? I could also make it out of the actual tube but was looking for a quick turnaround. Thanks!

    Difficult to suggest without knowing your location. If in India there are a large number of solenoid coil manufacturers who can give you one. You can wind a coil yourself. Probably 500 gms of enamelled Copper wire 0.5 or 0.6 mm dia wound over a 30 cm mandrel would do the job. You have to work out the voltage needed from available tables.
