It was reversed 65 million years ago. This is an approximate answer.

Ah, but given the category list this appears to ask about our planet's magnetic field. In which case, "normal" with respect to what?

I think it was normal

What causes reversed polarity in a 110 volt receptacles?
Improperly wired receptacle is the normal cause.
Magnetic patterns on the ocean floor were puzzling because they?
because they showed alternating bands of normal and reversed polarity.
Where can Alternating parallel bands of normal and reversed magnetic polarity are found in the basaltic bedrock on either side of the?
Mid-Atlantic ridge
If you wanted to trace the creation of tectonic plates using magnetic bands of normal and reversed polarity your best place to measure the magnetic stripes would be?

Describe how the polarity of earth's magnetic field is recorded in the sea floor?
The position of Earth's magnetic field changes over geologic time, pole is located near Earth's North Pole, a condition called normal polarity.
On the real ocean floor alternating stripes of normal and reversed polarity are not all of equal width. What does this tell you about the lengths of time represented by normal and reversed polarity?
It would indicate that the length of time between reversals is not predictable.
What causes reversed polarity in a 110 volt receptacles?
Improperly wired receptacle is the normal cause.
Differentiate between the terms reversed polarity and normal polarity?
Normal polarity is for the power to normally go from positive to negative, reverse polartity is to change the positive to a negative and the negative to a positive so the power goes the other way.
Scientists used the pattern of alternating normal and reversed polarity in rocks to create the geomagnetic?
time scale
Magnetic patterns on the ocean floor were puzzling because they?
because they showed alternating bands of normal and reversed polarity.
Reversed polarity is when?
In a normal distribution system, one wire is always connected to earth. Reverse polarity occurs when the live and neutral conductors on a system become reversed or 'swapped over'. It's a very dangerous situation with serious safety implications.
Approximately how long ago did the current normal polarity begin?

Mid-Atlantic ridge
Which is an example of reverse polarity?
Reverse polarity means that the direction of an energy flow is opposite of normal. In house wiring, it would mean that the hot wire (in the US, the black wire) was crossed with theneutral wire (in the US, white wire). Appliances would still function, but the flow of current is reversed (and unsafe)
How long ago did the current normal magnetic polarity begin?
780,000 years ago

Did the earth experience normal or reverse polarity 1.5 million years ago?
Normal polarity.
