Connect the charging cable and mouse to the iMac for 60 seconds, then disconnect the mouse from the cable.

If that doesn't help? Dig out, barrow or buy an inexpensive USB mouse to help reconnect your wireless the mouse.

Just to add to my colleagues @ den.thed advise
If you are using an Apple Magic Mouse, make sure the switch underneath is on and green is visible.
Connect the mouse to your Mac with its charging cable directly to the computer , leave it connected for about one minute, then disconnect it.
Apple says this charges the mouse and pairs it with the Mac. (Apple Support)
Then open Apple menu >> System Settings >> Bluetooth and check whether the mouse appears and shows as connected.
If it does not, make sure Bluetooth is turned on and check whether the mouse appears in the Bluetooth device list. (Apple Support)
If the mouse connects but does not remain connected, Apple also recommends checking for possible wireless interference from other wireless devices. (Apple Support)
Apple's full troubleshooting instructions are here: If you can't connect your Magic Mouse to your Mac
If your mouse is not an Apple Magic Mouse, tell me its make and model, because the appropriate troubleshooting steps will be different.
