This page has the Oman Au Puzzle Solution.

This page has the walkthrough/solution to the Magnesis Puzzle.

Interact with the Pedestal to get the Magnesis Rune
There is a gate, but it's locked
- Use Magnesis to lift the heavy panels on the floor, revealing a hole where Link can drop through.
Run parallel to the stream and climb the stairs to emerge on the other side of the gate.
There is a big wall which Link can't climb. Use Magnesis to move a panel in that wall and break the wall
Use the panel to shield yourself between you and the Guardian's attacks.
Push the Guardian to the water, using the same loose wall panel. When the Guardian falls in the water, it is killed.
There is a metal plate that acts as a bridge between two platforms. Go through it, then use your Magnesis to move it to the next gap.
Pull a Metallic Treasure Chest from a platform on the wall to your left towards you and get the loot inside.
Use Magnesis to pull the big doors open.
Speak to the monk to complete the challenge.
