I am a beginner and so far I have used the magnetometer blocks of codes but I don’t know how to see the flux density changes by placing a magnet toward the phone. I want to build an app that enables users to draw a pattern by using a magnet near the phone canvas to pick up the pattern on the phone screen. something exactly like this video.

Can you share a link to your project? That way someone can give advice or help you fix anything that’s not working. ---

yeah here is the link https://x.thunkable.com/copy/dfcb1bd87806095b24c895dcb3eebbb6 in fact, I want to draw a pattern of the magnet that I am moving on top of the phone. I can see the changes in flux density screen when moving the magnet, but I don’t know how can I draw on the canvas. ---

> [@khaji.masoudp1](#): > > [Thunkable](https://x.thunkable.com/copy/dfcb1bd87806095b24c895dcb3eebbb6) I’m not sure either. I tried these blocks and my phone vibrated in Thunkable Live but nothing appeared on the screen: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/8/d/8d82ffafc402ab02ddcd0802eec69a9a82b3da7a.png) Ah, it needed the “When Canvas Loads” block: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/0/c/0c841dcbf9c1a8d5e8d22901f219f20c69385799.png) ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/8/7/875b96dd1ef23ba1a512bf008d6f404b16a8395b.png) ---

Finally, I could figure it out, By activating sprite drawing and using x and y flux densities for sprite’s x and y inputs. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/2/a/2a9f85a0e7370cccd02248449336b527a17250de.png) Thank you for follow up ---
