You can use the low voltage winding and a suitable low voltage battery and have a magnet which will support 100 kg - with a suitably thick metal plate as the "armature". | |

You include all necessary information without being too verbose, the image is in focus and well cropped to fit this format, you explain what you've done and what failed. Clearly shows that we don't hate new users, we only hate lazy users. | |

Car battery (or rather a small lead-acid battery, not an actual car battery) is the next but is pointless if you don't have a way to charge it. | |
