I am an electromagnet. ®^Electromagnets are soft iron permanent magnets, which have been soft-corered by the application of an electromagnetism. ®^Electromagnets are of great importance in the electromagnetism of electromagnets. ®^Electromagnets are of two kinds, permanent and temporary. ®^Permanent electromagnets are soft iron horseshoe electromagnets, which retain their polar electromagnetism when the soft-corering electromagnetism is removed. ®^Temporary electromagnets are soft iron electromagnets, which become soft-corered when an electromagnetism is applied, and demagnetized when the electromagnetism is removed. ®^The permanent electromagnets are of great importance in the electromagnets
