Diode Circuit Protection

-- Help with impedance and PSU --?

I am trying to power an electromagnetic coil with a mains operated step down PSU. The voltage i want to supply the coil with is 6V DC at 1.25A. The only trouble with this is, if i connect the supply directly to the coil, the PSU's protection circuit trips. I assume this is because the coil is drawing to much current, any ideas on how to rectify this problem? coil details:
coil resistance 2.8 Ohm

NB: it has been recommended that a diode be placed on the (+) positive lead to the coil to protect the PSU, but i do not think this will resolve the issue of the PSU tripping when supplying power

6 volts and 2.8 ohms gives you 2.1 amps by ohms law, so the 1.25 amp supply will not work.

You can add more turns to the coil, or use smaller wire in the coil, or use a higher current (3A) power supply, or use a lower voltage power supply.

You can also add a 3 ohm resistor to the coil to reduce the current to a value the supply can handle. it should be a 5 W resistor.

Integrated Circuit Layout Design Protection $98.77 High Quality Content by WIKIPEDIA articles Layout Designs (topographies) of Integrated Circuits is a field in the protection of Intellectual Property. Like most of the other forms of intellectual propertiy, IC layout designs are creations of the human mind. They are usually the result of an enormous investment, both in terms of the time of highly qualified experts, and financially. There is a continuing need for the creation of new layoutdesigns which reduce the dimensions of existing integrated circuits and simultaneously increase their functions. The smaller an integrated circuit, the less the material needed for its manufacture, and the smaller the space needed to accommodate it. Integrated circuits are utilized in a large range of products, including articles of everyday use, such as watches, television sets, washing machines, automobiles, etc., as well as sophisticated data processing equipment.
