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 Spending Money - Your Daily Prayer - May 29
No one is immune to the negative hold that money can have on our hearts in plenty or in want. I am a spender. I like to shop and get new things. However, God has taught me throughout my life to pray about my spending and to listen to the still, small voices that lead me in my financial decisions. God desires us to live a life of generosity, putting God before money. We cannot serve both God and money.
