Class7_Science_Electric Current and its Effects_Electric Components
In the 19th century, James Joule studied a property, which says that "when an electric current flows through the filament of a bulb, it generates heat, and so the bulb becomes hot". This property is named the heating effect of electric current.
An electromagnet is formed due to the magnetic effect of electric current. This magnetic effect
of electric current was discovered by Hans Christian Oersted. Once, while preparing for a lecture, he noticed that there was a deflection in the needle of a magnetic compass kept near a
wire that was connected to a battery. This deflection occurred every time the battery was switched on and off. He realized that a magnetic field is created around a current-carrying wire in a circuit.

A Prayer for When You Feel Lost - Your Daily Prayer - April 27
When we feel lost, God is our true north. He is the one who can lead us where He wants us. It is so easy to get caught up in listening to the world, so sometimes, it is best to shut it out to create a quiet space for God to work.
