The Coin Magnet is a power-up in Subway Surfers. When collected, the character grabs it and automatically collects every he/she passes by, even if a coin is not in his/her path. This is the ideal power-up if they want to get coins very rapidly.
When the player collects a Jetpack while the coin magnet is active, it will collect the first few coins on the ground before reaching the sky.
It will collect all coins in the air when a Jetpack is active until the coin magnet wears off.
However, they cannot collect coins on the ground with a coin magnet when up in the air. Instead, they collect the coins in the air.
Similarly, they cannot collect coins on the ground when on top of a big tunnel with coins, neither can they do this vice versa.
They also cannot attract coins on the ground when using a Power Jumper.
But, they will start attracting the coins on the ground when you first touch the ground.
It is one of the most useful power-ups/items in the entire game.
A normal magnet only attracts steel in reality, but the magnet in this particular game and other games similar to it only attracts coins.
It has the appearance of a horseshoe magnet.
Since coins contribute to the final score, it is also an essential power-up in receiving highscores.
