Magic Keyboard for iMac 24 handwriting input source

Sorry, your question is not clear.

The Magic Keyboard, is just a keyboard, it has no handwriting support of any kind.

To be able to handwrite in certain apps you need a device that can accept the handwriting input, such as a track pad or tablet and software that can translate the handwriting to text.

You can add a handwriting option if you Select Chinese as the text input language, but this only accepts Chinese characters on an onscreen area and is independent from the type of keyboard you have. It uses a trackpad to capture the movements to draw the Chinese characters.

Are you perhaps talking about typing text with the keyboard using a handwriting type font?
