a mandatory field in a database is one created in a table as "Not null". This means, there is a "rule" on the field that when data is inserted into the table, this field cannot be empty. If it is, then the insert errors. Here's part of a table definition in my database. These field are are required to be populated when inserting into this table. ATTR_DESC_01 CHAR(2) DEFAULT SYSTEM NOT NULL
, ATTR_DESC_02 CHAR(2) DEFAULT SYSTEM NOT NULL
, ATTR_DESC_03 CHAR(2) DEFAULT SYSTEM NOT NULL
, ATTR_DESC_04 CHAR(2) DEFAULT SYSTEM NOT NULL
, ATTR_DESC_05 CHAR(2) DEFAULT SYSTEM NOT NULL
, ATTR_DESC_06 CHAR(2) DEFAULT SYSTEM NOT NULL
, ATTR_DESC_07 CHAR(2) DEFAULT SYSTEM NOT NULL
, ATTR_DESC_08 CHAR(2) DEFAULT SYSTEM NOT NULL
, ATTR_DESC_09 CHAR(2) DEFAULT SYSTEM NOT NULL
, ATTR_DESC_10 CHAR(2) DEFAULT SYSTEM NOT NULL
, PARTITION_NBR SMALLINT NO DEFAULT NOT NULL

A radial magnetic field ensures that the plane of the coil (rotating within the magnetic field, in say a DC motor) is always flat within the external magnetic field ensuring maximum torque in (nearly) all positions. Hope this helps!
A pole slip occurs when a motor or generator cannot maintain synchronicity. This occurs because the field excitation is too low.

What is said is a voluntary act and no accuracy , while what is meant is either voluntary or mandatory and relatively accurate in nature
