I am engineer and have a question about magnet while just playing with magnets. Let say I create permanent magnet by investing 1 Watt energy by electrical process then I can displace virtually infinite amount of iron by that magnet.(I am not repelling that object) and as per principle that another object also work as magnet and that object also can move infinite amount of irons and so on. Isn't it paradox?Or any explanation?
