3-12V DC 0.6-2.5A suction type electromagnet voltage frame type electromagnet

Power test machine:
3V DC , CURRENT 0.6A
6 VDC , CURRENT 1.2 A
12VDC , CURRENT 2.5A
Resistance: 3.5 OHM
Weight: 53 G
Length: 120 MM (approximately)
3V power is too small, 6V power very big, 12V power is very powerful, easy to heat should not suitable for work for a long time),
the higher the voltage, power is greater, the greater the power, but also High heat
